Hello. My son, Hayden, has a deletion at 12q12 (37,840,869-41,270,251). The genes that have been deleted (11 total) are KIF21A, ABCD2, SLC2A13, LRRK2, CNTN1, PDZRN4, GLT8D3, YAF2, ZCRB1, PPHLN1, and PRICKLE1.Hayden is a special case though because he also has a deletion at 4q21.22q21.23 consisting of 15 genes. He is now 8 months old and has feeding issues, hypotonia, is not rolling, sitting, etc. he weighs 16 pounds and is 25 inches long. He just made it to the 1st %ile! Hayden was found to be aspirating at 2 weeks old and at 4 weeks had g-tube and funduplication surgery. He has small hands and feet, microphalus (small penis), and "dysmorphic features" according to docs, but we and a him thinks he is beautiful.:) we do feeding therapy once a week, physical therapy starting in 2 weeks. He is overall very healthy. He has pulmonary stenosis, but it's very mild, don't have to see cardio for a year. He also has Kallman's syndrome which means he is lacking the hormones LH and,FSH which assist in puberty and baby making. He is completely deaf in his left ear. Let's see...i think that's all...sometimes I forget all the crap he is dealing with ;) my email address is email@example.com if u would like to email me. Blessings to you all. So happy to have found you.
