Genes affected

WAC (HGNC:17327): (WW domain containing adaptor with coiled-coil) The protein encoded by this gene contains a WW domain, which is a protein module found in a wide range of signaling proteins. This domain mediates protein-protein interactions and binds proteins containing short linear peptide motifs that are proline-rich or contain at least one proline. This gene product shares 94% sequence identity with the WAC protein in mouse, however, its exact function is not known. Alternative splicing results in multiple transcript variants.

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 10-28616337-G-A is Pathogenic according to our data. Variant chr10-28616337-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 219140.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr10-28616337-G-A is described in Lovd as [Pathogenic].
