Autoszomális recesszív
Caused by loss-of-function changes in both copies of RDH12, an enzyme that protects photoreceptors from toxic by-products of light-sensing chemistry. Each parent usually carries one changed copy.
Tünetek és jelek
Severe loss of vision usually appears in infancy or early childhood, often with nystagmus (involuntary eye movements).
Mit változtat a diagnózis
Regular eye reviews, low-vision aids and educational support. Gene therapies for RDH12 are under investigation, so a confirmed genetic diagnosis may open access to clinical trials. Genetic counselling and carrier testing of relatives clarify recurrence risk.
