Genetic testing for Sorsby’s fundus dystrophy

Open access


We studied the scientific literature and disease guidelines in order to summarize the clinical utility of the genetic test for Sorsby’s fundus dystrophy (SFD). SFD is caused by variations in the TIMP3 gene. Prevalence is, currently unknown. SFD has autosomal dominant inheritance. 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.
