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.

MPDZ Gene-Disease associations (from GenCC):

• hydrocephalus, nonsyndromic, autosomal recessive 2

  Inheritance: AR Classification: STRONG, MODERATE, LIMITED Submitted by: Laboratory for Molecular Medicine, Ambry Genetics, Labcorp Genetics (formerly Invitae), Genomics England PanelApp, G2P

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.55).
