Genes affected
SPATA7 (HGNC:20423): (spermatogenesis associated 7) This gene, originally isolated from testis, is also expressed in retina. Mutations in this gene are associated with Leber congenital amaurosis and juvenile retinitis pigmentosa. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2010]

Submissions by phenotype

Leber congenital amaurosis 3 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJul 09, 2022In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 1014980). This variant has not been reported in the literature in individuals affected with SPATA7-related conditions. This variant is present in population databases (rs140287375, gnomAD 0.01%). This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 85 of the SPATA7 protein (p.Arg85Gly). -
