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.

The c.6059C>T (p.T2020I) alteration is located in exon 45 (coding exon 45) of the MPDZ gene. This alteration results from a C to T substitution at nucleotide position 6059, causing the threonine (T) at amino acid position 2020 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
