Genes affected

WBP2 (HGNC:12738): (WW domain binding protein 2) The globular WW domain is composed of 38 to 40 semiconserved amino acids shared by proteins of diverse functions including structural, regulatory, and signaling proteins. The domain is involved in mediating protein-protein interactions through the binding of polyproline ligands. This gene encodes a WW domain binding protein that is a transcriptional coactivator of estrogen receptor alpha and progesterone receptor. Defects in this gene have been associated with hearing impairment. [provided by RefSeq, Jan 2017]

WBP2 Gene-Disease associations (from GenCC):

• hearing loss, autosomal recessive

  Inheritance: AR Classification: SUPPORTIVE, LIMITED Submitted by: Orphanet, ClinGen
• hearing loss, autosomal recessive 107

  Inheritance: Unknown Classification: LIMITED Submitted by: Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.32665545).
