Abstract We studied the scientific literature and disease guidelines in order to summarize the clinical utility of genetic testing for gyrate atrophy of the choroid and retina (GACR). GACR is inherited in an autosomal recessive manner, and has a prevalence of 1/50000 in Finland. In the international literature there are approximately 200 biochemically confirmed cases. GACR is caused by mutations in the OAT gene. Clinical diagnosis involves ophthalmological examination, electrophysiological testing (electroretinography - ERG), coherence tomography and assay of ornithine levels in body fluids. The genetic test is useful for confirming diagnosis, as well as for differential diagnosis, couple risk assessment and access to clinical trials.

Familial Exudative Vitreoretinopathy

Abstract We studied the scientific literature and disease guidelines in order to summarize the clinical utility of genetic testing for familial exudative vitreoretinopathy (FEVR). There is insufficient data to determine the prevalence of FEVR. Variations in the FZD4 (OMIM gene: 604579; OMIM disease: 133780), TSPAN12 (OMIM gene: 613138; OMIM disease: 613310) and ZNF408 (OMIM gene: 616454; OMIM disease: 616468) genes have autosomal dominant inheritance, whereas variations in LRP5 (OMIM gene: 603506; OMIM disease: 601813) have autosomal dominant or recessive inheritance and variations in NDP (OMIM gene: 300658; OMIM disease: 305390) have X-linked inheritance. Clinical diagnosis is based on clinical findings, family history, ophthalmological examination, fundoscopy, slit-lamp examination and fluorescein angiography.
