Autozomálně recesivní
Caused by changes in both copies of TTLL5, an enzyme that modifies the tubulin skeleton of cilia, including the connecting cilium of photoreceptors and the sperm tail.
Příznaky a projevy
Gradual loss of central vision and colour vision from a cone or cone-rod dystrophy, often starting in adulthood, although some people have early-onset disease. Some men with certain changes have reduced fertility because their sperm move poorly.
Co se diagnózou změní
Regular eye review and low-vision support, with fertility advice for men where needed. Carrier testing of relatives and genetic counselling are available.
