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 missense change has been observed in individual(s) with deafness (PMID: 26416264). It has also been observed to segregate with disease in related individuals. For these reasons, this variant has been classified as Pathogenic. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on PDZD7 protein function. This variant is present in population databases (rs148695069, gnomAD 0.008%). This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 103 of the PDZD7 protein (p.Gly103Arg). -
