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.

WAC Gene-Disease associations (from GenCC):

• DeSanto-Shinawi syndrome

  Inheritance: AD Classification: DEFINITIVE Submitted by: ClinGen
• DeSanto-Shinawi syndrome due to WAC point mutation

  Inheritance: AD Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: G2P, Orphanet, Labcorp Genetics (formerly Invitae), Illumina

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
