Genes affected

GAS2 (HGNC:4167): (growth arrest specific 2) The protein encoded by this gene is a caspase-3 substrate that plays a role in regulating microfilament and cell shape changes during apoptosis. It can also modulate cell susceptibility to p53-dependent apoptosis by inhibiting calpain activity. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2017]

GAS2 Gene-Disease associations (from GenCC):

• hearing loss disorder

  Inheritance: AD Classification: LIMITED Submitted by: Ambry Genetics
• hearing loss, autosomal recessive 125

  Inheritance: AR Classification: LIMITED Submitted by: Ambry Genetics

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.0604 is higher than 0.05.
