Genes affected

STRC (HGNC:16035): (stereocilin) This gene encodes a protein that is associated with the hair bundle of the sensory hair cells in the inner ear. The hair bundle is composed of stiff microvilli called stereocilia and is involved with mechanoreception of sound waves. This gene is part of a tandem duplication on chromosome 15; the second copy is a pseudogene. Mutations in this gene cause autosomal recessive non-syndromic deafness. [provided by RefSeq, Jul 2008]

ENSG00000284772 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -7 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BP6: Variant 15-43615550-T-C is Benign according to our data. Variant chr15-43615550-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 227964.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr15-43615550-T-C is described in Lovd as [Likely_benign].
• BP7: Synonymous conserved (PhyloP=-0.663 with no splicing effect.
