| Identified Mutation |
SER190TER |
| Remarks |
Clinically affected; onset of symptoms around 14-16 years of age; diagnosed at 28 years of age by ophthalmologist; diminishing visual acuity; direct sequencing of CHM gene revealed a nonsense mutation in exon 5 (569 C>T, former nomenclature: 599C>G, S190X); assistive device: white cane; brother and second cousin are also affected (not in repository); see GM25421 for donor fibroblast line. |
