Genes affected

PDZD7 (HGNC:26257): (PDZ domain containing 7) This gene encodes a ciliary protein homologous to proteins which are mutated in Usher syndrome patients, and mutations and translocations involving this gene have been associated with two types of Usher syndrome. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2010]

This variant is present in population databases (no rsID available, gnomAD 0.004%). In 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 output the following: SIFT: "Deleterious"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0". The serine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 1507443). This variant has not been reported in the literature in individuals affected with PDZD7-related conditions. This sequence change replaces arginine, which is basic and polar, with serine, which is neutral and polar, at codon 1005 of the PDZD7 protein (p.Arg1005Ser). -
