| Remarks |
Clinically affected; onset of symptoms at 14 years of age; diagnosed at 61 years of age; DNA sequencing through exons 5 and 6 of the CHM gene using genomic DNA from the subject's white blood cells revealed a hemizygous, probable highly-penetrant disease-causing variant: Arg270Stop CGA>TGA and a hemizygous non-disease-causing variant Ala117Ala GCA>GCG; family history: subject has one brother affected with choroideremia (GM25399-lymph,GM25400-fibro) and one brother unaffected by the disease (not in repository); fibroblast is GM25386. |
