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 Benign. Variant got -10 ACMG points.

• BP6: Variant 10-28533659-G-GGGC is Benign according to our data. Variant chr10-28533659-G-GGGC is described in ClinVar as [Likely_benign]. Clinvar id is 1335861.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00908 (1371/150948) while in subpopulation AFR AF= 0.0315 (1300/41216). AF 95% confidence interval is 0.0301. There are 27 homozygotes in gnomad4. There are 643 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 1371 AD gene.
