Autozomálně recesivní
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.
Příznaky a projevy
Severe loss of vision usually appears in infancy or early childhood, often with nystagmus (involuntary eye movements).
Co se diagnózou změní
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.
