Laboratory for Molecular Medicine,Partners HealthCare Personalized Medicine RCV000037847 SCV000061509 benign not specified 2013-04-24 criteria provided, single submitter clinical testing This variant is not expected to have clinical significance. Although there is so me controversy in the literature over the significance of this variant, after a thorough review of the following papers (Estivill et al. 1998; Marlin et al. 200 1; D'Andrea et al. 2002; Thonnissen et al. 2002; RamShankar et al, 2003; Wang et al. 2003; Toth et al, 2004; Chaleshtori et al. 2006; Dahl et al, 2006; Palmada et al, 2006) we conclude that the Arg127His variant is not causative for hearing loss. This conclusion is mainly due to its common (17.5%) occurrence in an Asia n Indian control population (RamShankar et al, 2003) and homozygous and compound heterozygous identification in individuals with normal hearing (Marlin et al. 2 001; RamShankar et al, 2003; Dahl et al, 2006). In addition, it has been reporte d in two large population studies; the Arg127His variant has been identified in has been identified in 0.3% (26/8600) of European American chromosomes by the NH LBI Exome Sequencing Project and 0.23% (5/2178) chromosomes by the 1000 Genomes Project (; dbSNP rs111033196). In summary, this variant is meets our criteria to be classified as benign due to its high freque ncy in the general population and its presence in the homozygous state in unaffe cted individuals.

GeneDx RCV000589067 SCV000977442 benign not provided 2018-06-08 criteria provided, single submitter 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.
