Females are only supposed to be "carriers" of the ABCD1 gene defect, but symptoms of AMN still manifest themselves.
My Mum is primarily restricted to a scooter. She can still transfer herself on and off seats/devices, and can walk a little, but not unaided. She also has tremors in her arms and hands.
She was diagnosed with MS years ago before gene testing narrowed her ailment down to AMN, but I don't know if she's been officially re-diagnosed with AMN. It seems obvious that it would be right to, however.
