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 creates a premature translational stop signal (p.Arg1071*) in the MPDZ gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in MPDZ are known to be pathogenic (PMID: 23240096, 28556411). This variant is present in population databases (rs376078512, gnomAD 0.01%). This premature translational stop signal has been observed in individual(s) with MPDZ-related conditions (PMID: 28556411). ClinVar contains an entry for this variant (Variation ID: 548149). For these reasons, this variant has been classified as Pathogenic. -
