Genetic testing for Norrie disease

We studied the scientific literature and disease guidelines in order to summarize the clinical utility of genetic testing for Norrie disease. The disease is caused by variations in the NDP gene. Its prevalence is currently unknown. Inheritance is X-linked recessive. Clinical diagnosis is based on clinical findings, color vision testing, optical coherence tomography, ophthalmological examination and electroretinography. The genetic test is useful for confirming diagnosis, and for differential diagnosis, couple risk assessment and access to clinical trials.
