Genes affected

MPDZ (HGNC:7208): (multiple PDZ domain crumbs cell polarity complex component) The protein encoded by this gene has multiple PDZ domains, which are hallmarks of protein-protein interactions. The encoded protein is known to interact with the HTR2C receptor and may cause it to clump at the cell surface. Multiple transcript variants encoding different isoforms have been found for this gene.

This sequence change replaces aspartic acid, which is acidic and polar, with tyrosine, which is neutral and polar, at codon 801 of the MPDZ protein (p.Asp801Tyr). This variant is present in population databases (rs758473798, gnomAD 0.03%), including at least one homozygous and/or hemizygous individual. This variant has not been reported in the literature in individuals affected with MPDZ-related conditions. ClinVar contains an entry for this variant (Variation ID: 522684). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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. -
