Abstract We studied the scientific literature and disease guidelines in order to summarize the clinical utility of genetic testing for Usher syndrome (USH). USH is mostly transmitted in an autosomal recessive manner and is caused by variations in the ADGRV1, CDH23, CIB2, CLRN1, HARS, MYO7A, PCDH15, PDZD7, USH1C, USH1G, USH2A, WHRN genes. Prevalence is estimated to be 1:30,000. Clinical diagnosis is based on audiogram, vestibular tests, visual acuity test, fundus examination, color test, optical coherence tomography and electroretinography. The genetic test is useful for confirming diagnosis, and for differential diagnosis, couple risk assessment and access to clinical trials.

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.

Abstract We studied the scientific literature and disease guidelines in order to summarize the clinical utility of genetic testing for Mendelian myopia (MM), a large and heterogeneous group of inherited refraction disorders. Variations in the SLC39A5, SCO2 and COL2A1 genes have an autosomal dominant transmission, whereas those in the LRPAP1, P3H2, LRP2 and SLITRK6 genes have autosomal recessive transmission. The prevalence of MM is currently unknown. Clinical diagnosis is based on clinical findings, family history, ophthalmological examination and other tests depending on complications. The genetic test is useful for confirming diagnosis, and for differential diagnosis, couple risk assessment and access to clinical trials.
