Genes affected
RIPOR2 (HGNC:13872): (RHO family interacting cell polarization regulator 2) This gene encodes an atypical inhibitor of the small G protein RhoA. Inhibition of RhoA activity by the encoded protein mediates myoblast fusion and polarization of T cells and neutrophils. The encoded protein is a component of hair cell stereocilia that is essential for hearing. A splice site mutation in this gene results in hearing loss in human patients.

The c.3166G>T (p.V1056F) alteration is located in exon 23 (coding exon 22) of the FAM65B gene. This alteration results from a G to T substitution at nucleotide position 3166, causing the valine (V) at amino acid position 1056 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
