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.

GeneDx
Significance:Benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

Significance:Benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

p.Ala1000Ala in exon 21 of FAM65B: This variant is not expected to have clinical significance because it does not alter an amino acid residue, is not located wi thin the splice consensus sequence, and has been identified in 67.95% (424/624) of East Asian chromosomes by the Exome Aggregation Consortium (ExAC, http://exac .broadinstitute.org; dbSNP rs9358802).
