Dear Dent mothers, fathers and patients, We have worked hard to create the survey at RDCRN (Rare Disease Clinical Research Network - NIH sponsored). No good response yet - only about 10 patients finished. Link below, please consider!!! This is an easier, faster form of research and allows people from all over the world to do it. You will be asked to join contact registry and then do the survey. Good luck! Takes 10 min for moms and a little longer for patients - parents can do that one as well, even if kids are over 18! Please remember, the outcomes of this disease depend on your participation. It is a slow process, but if there is no process, there will be no outcome. My warmest regards, Lada

Hi Lada We are in the UK - I met you when you came to the RKD symposium 2 years ago. My son is on the Dents registry and we have filled out all the forms again recently for Barbra Seide... He is also now seeing a metabolic specialist, so if you let me know what tests you require, I can ask at our next appointment in October.

What is his serum phosphorus? If you are in the US, we could include him in phosphorus study and measure phosphorus related hormones which I believe are extremely important for growth but not routinely measured. Lada

My son Zander was dx with dents at 5 yrs. Now is 10.5 yrs. He is 4 ft tall my side.of family 8s short stature. His dad 6ft 8 inch. We started endocrinology and the hand xray. Awaiting MD to get back to me from Stanford University. He had been seen at Stanford for 5 yrs now and luckily dr.potter there was able to dx him early and her him on chlorthalidone. (Sp) which he has been on since.but with varying dosages. He is also skinny. His wt is 56 lbs finally and that has taken 3 yrs to get there. As far as po4 he takes 750mg bid. Neutral phos. 2000 units.vit d just restarted that last 3.months. daily. 80 me kcl 30 20 30 dose during day to combat chlorthaladone k wasting. Avg. K level is 3.3-3.5. Lab about every 3 months. Also takes a milo ride to kick up his k levels. I have Zander in the study, or at least I returned the papers and hopes his data helps research. My concern is the obvious future kid. Failure, and transplant if and when it comes to that for him, but his overall fitting in. Being so short does not help in school. To make learning an issue he.was a.late talker 3 years old to make a 5 word sentence. Now he won't shut it. But he has adhd, and that lack of concentration and taking care of his disease in his future worries me. He is well aware of all his med and the rationale for their continued use and dose changes. It seems as if.from reading other posts the correlation of growth and learning is a factor is this disease process. Zander mom T

I have the hypothesis that possibly Dent and Lowe patients don't get enough phosphorus in their bone as they hit the potential growth spurt (because they lose some through their kidney). One way to prove that is to show that the major hormone that causes release of phosphorus in the urine is below normal in Dent. So far 3/4 adult Dent patients in my study have it. Now I want to see if children (in particular) children in puberty have that as well. Growth hormone also increases phosphorus absorption in the kidney, and it's possible that that is the way it works. We don't know which effect it has on the bone of Dent kids. Lada

I have three children, one with Dent's. Both of my two children without Dent's are tall...medium to extra large framed. My son with Dent's is thin, small framed, and definetly grew at a different rate. For a frame of reference, my 12 year old is 5'10 and 170 pounds. My 15 year old with Dent's is 5'6 and 110 pounds.

21 Jan 2015, 10:30 PM

No, restriction is advised only if oxalate is elevated. The elevation could also be a result of calcium restriction in diet. Calcium should not be restricted. If less calcium is eaten, more oxalate is absorbed. My view is that possibly Dent patients do not get enough phosphorus, that is why I am studying phsophate regulating hormones for Dent in my FGF Study for Dent disease. We will hopefully learn something from it. I have just looked up our registry data. Few patients have oxalates in 50-60 range. Not most common but possible. Lada

Do you recommend a low oxalate diet in Dent's even if the oxalate level is normal?

Posted by LadaBL
21 Jan 2015, 09:39 PM

High oxalates are not common for Dent. However, sometimes even levels this high can come from dietary sources, but you could have him tested for primary hyperoxaluria. It is very important to minimize oxalate in diet. Did you review it with the nephrologist or a nutritionist? High doses of vitamin C can also give you high oxalate, make sure he is not getting that. We also have a center for primary hyperoxaluria if you would need genetic testing. Where did you get with this so far? Lada

Dear Jack, Sorry for the late reponse. We were terribly busy submitting all the required paperwork that would allow us further funding for Dent disease, which we have finally achieved. I am also personally very busy on my FGF Dent study, which is giving me some exciting preliminary results I will be able to share. Now we have 5 more years of funding and we plan to use it in the best way possible. There is a difference between the Contact registry and the Dent Disease Registry. Contact Registry only has the contact information, whereas the disease registry has the particular information about your disease - blood tests, urine tests, which are stored de-identified. Meaning by number and not your name.This information can later be used to draw some conclusions on disease progression, prognosis etc. Proudly, we started with 10 and now have 130 pts in our Dent Disease Registry. Did you get in contact with our coordinator Barbara Seide? Lada

Hi Jack. Welcome to the forum. Lada would be in a better position to answer your questions as I am no doctor. But as a mom of a 22 year old (asymptomatic like you) Dent patient that has known since he was 3 years old, I would say, yes, the severity and speed of loss of kidney function varies from one individual to another. And, unfortunately, like other kidney diseases, your kidney function in most cases keeps decreasing gradually throughout the years and you do not feel any symptoms until your kidney function is extremely low (in need of dialysis or transplant). My son has been taking a variety of meds since he was 3 (allopurinol, thiazide, fosinopril, potassium citrate and now crestor), but I do not necessarily think they have really helped in slowing down the disease. We will never know. I agree with your doctors and Jay, that probably the best thing is to eat healthy (low protein, low salt) and drink lots of water.

Hello, I am new to the Rareshare community and sort of new to Dent's. I have been aware of a Kidney problem since I was 11 (I'm now 27) when it was noticed in a standard medical test for a Visa that I had very high protein in my urine. Following this I had a series of further tests, and a biopsy and was finally told that I had "probable Dent's Disease" in my early teens. The expectation was that Genetic Testing would be performed but the University (in the UK where I am from) didn't have enough samples / money to go through with it. I have had a succession of Nephrologists since finishing with my Paediatrician, all of whom have given me different advice, pills, no pills, low oxylate low protein diets, no diets. Excluding a 1-1.5 year period where I took allopurinol, Amiloride, Bendroflumethiazide, and Ramipril I have taken no meds. The only proactive advice I received prior to the medications was to drink plenty of fluids and eat a diet that is not high in salt. I had always drunk lots and so this wasn't difficult. As such as a teenager / adult I have maintained a pretty constant intake of appx. 5-7litres per day. My latest Nephrologist recommended that I have the genetic testing done, as then it would confirm the appropriate direction for the Treatment. This came back positive and I have Dents Disease 1. This new outlook has spurred me to take a more proactive approach myself, so I have joined the Contact Registry etc (Lada please let me know as I think I m supposed to be joining more than one registry having read some of the posts on here). One of the main interesting things that I have noticed in reading the forums is that lots of people seem to be relatively asymptomatic (as am I) and I would be interested to know if this reveals anything in particular about the severity of the disease in each individual. Look forward to hearing from you all, J

Dent Registry

I am happy to inform everyone that Dent Registry is started at Mayo clinic. We hop that we can gather more information and advance knowledge on the disease and therapy.


We are looking to enrol all patients with Dent all over the world. If you are interested, please check out our website. Please feel free to ask any questions.





Clinical Trials

Cords registry

CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access.

Enrolling is easy.

  1. Complete the screening form.
  2. Review the informed consent.
  3. Answer the permission and data sharing questions.

After these steps, the enrollment process is complete. All other questions are voluntary. However, these questions are important to patients and their families to create awareness as well as to researchers to study rare diseases. This is why we ask our participants to update their information annually or anytime changes to their information occur.

Researchers can contact CoRDS to determine if the registry contains participants with the rare disease they are researching. If the researcher determines there is a sufficient number of participants or data on the rare disease of interest within the registry, the researcher can apply for access. Upon approval from the CoRDS Scientific Advisory Board, CoRDS staff will reach out to participants on behalf of the researcher. It is then up to the participant to determine if they would like to join the study.

Visit to enroll.

I am a nephrologist (kidney doctor) who works at NYU in New York City. National Institutes of Health has sponsored research of Dent disease starting Sept 2009 which includes, and starts with, forming Registry of Dent disease patients.



Dent disease manifests usually with low molecular weight proteinuria (loss of protein in the urine) and often with kidney stones or even calcifications of kidney. Significant number of patients develop kidney failure and need dialysis or transplantation.



Registry means collection of information on individual patients which is then stored, anonymously, in one database. That allows us to analyze collected information on large group of Dent patients, which has never been done before, because physicians typically take care of only few Dent patients (usually 1-5).



Our website is, where you can look up the available information.

".Hi Lada. My 14 year old son has been diagnosed with Dent 1. He has losses of calcium, proteinura and hematuria. They are only giving him acalka and now Vitamin D. But he is not as tall as he should be for his age, and now two small bumps have come out on his chest. The doctor says this is normal growth but I am very concerned. Thanks for your answer.


Thanks. You can answer her that growth delay is common in Dent disease and that sometimes children get treated with growth hormone.

I have a question about Dent's Disease & its progression. I realize you can't predict what is going to happen with my son, but I am curious as to whether you have heard/seen any trends with regard to its progression. My son, Matthew, turns 15 years old next week. His creatinine is 1.2 as of today & he weighs approximately 114. His creatinine has been going up .1 for the past 4 labs. He has labs every 3-4 months. At this rate, if it keeps progressing at this rate, he will need a transplant before he reaches 20. I am very concerned. Are there any statistics? Could puberty cause the creatinine to increase at a faster rate & then maybe it may slow down as he gets older? What is the average age of transplant with this disease? Is there anything that has been found to slow the progression? Another thing.....can a carrier be a potential kidney donor? I have 4 daughters & 3 of them are Dent's carriers. Thank you so much for your time.


Dear Rosemary,



I would not worry about the transplant at this time, his kidney function is very good.


Carriers could theoretically be donors, however we are not sure if we recommend it or not.


If the donor has proteinuria or stones, it is probably not such a good idea. It has been done, however.


It would have to be decided on case to case bases by a transplant center.



As the child grows and gains muscle mass, the creatinine could increase.


Citrates have been shown to decrease progression on mice, nothing known with certainty on humans.


ACE inhibitors when significant albuminuria potentially beneficial, no data.


Thiazide diuretics? Unknown if affect progression.


You see, patients are asking us for advice but we have no data and cannot recommend.


Then we try to get data but patients are reluctant to participate in research!


And we go in circles.


In our study we are trying to see if phosphorus could be beneficial in reducing calcium in urine, kidney damage instead of thiazides that have side effects often difficult to tolerate.





We could talk on the phone this weekend, or Fri pm if you like, since this is so complex.

My 8 year old son and my 32 year old brother both have Dent's, and my brother has recently been placed on dialysis due to renal failure, and he is currently on the transplant list. I am a carrier of dent's, and have mild symptoms, excess protein in the urine, have had kidney stones several times, Am I a canidate to donate a kidney to either of them if I am a match?


This question has really not been answered properly as of yet.



We have heard of a mother who has donated the kidney to her son and both were doing well, however there is no clear recommendation.



If you actively form stones, and have significant stone on CT and have significant proteinuria, that is probably not a good idea.


I would say, you don't have absolute contraindication but a relative one and you would have to be evaluated by a transplant center.

Hi Lada,


Thank you for responding to my earlier question. My son is 8years old, and we have since stopped the enalapril because it was having absolutely no effect on him and was making him feel bad. We recently discovered that my brother, who is 32, has Dent's also, and he is in kidney failure and will be started on dialysis soon. We are hoping this is not typical and this is not the path that my son will go down. Does kidney failure usually onset this quickly with Dents pts? Our son is on the dent's registry and we are willing to enroll him in the study and I'm sure my brother would participate also.


It is quite common that the older relative gets a diagnosis only after a child is diagnosed.


This is a rare disease more unusual in children and pediatricians are better in making the diagnosis.



It is in the expected age range that your brother developed advanced kidney failure, however an early part of that age spectrum. Usually for Dent, dialysis is needed between 30 and 50, so this was early.



Our goal is to study more the disease and test interventions that could delay the progression of the disease. That is why we are doing this study.



The good news is that just because they have the same mutation, the disease does not have to behave in the same way in the two of them. Variability in the family is quite common.



I am glad you are in the registry. As soon as our consent form for children is approved, I will let you know. Unfortunatelly, for now we are not testing the patients with advanced disease if they have high PTH (parathyroid hormone) and your brother likely has it above normal. You can ask him if he knows, but he should definitely be in the registry for any further research and for better understanding of disease.
