GeneDx RCV000493634 SCV000582685 pathogenic not provided 2017-04-27 criteria provided, single submitter clinical testing The c.13374delA variant in the USH2 gene has been reported previously in the compound heterozygous state with a second USH2 variant in patients with Usher syndrome type II (Baux et al., 2007; Le Quesne Stabej et al., 2012). The c.13374delA variant causes a frameshift starting with codon Glutamic Acid 4458, changes this amino acid to a Aspartic Acid residue, and creates a premature Stop codon at position 3 of the new reading frame, denoted p.Glu4458AspfsX3. This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The c.13374delA variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). We interpret c.13374delA as a pathogenic variant.
Laboratory for Molecular Medicine,Partners HealthCare Personalized Medicine RCV000152565 SCV000201812 pathogenic Rare genetic deafness 2014-09-15 criteria provided, single submitter clinical testing The p.Glu4458fs variant in USH2A has been reported in four individuals with Ushe r syndrome, all of whom are compound heterozygous with a second pathogenic USH2A variant (Baux 2007, Stabej 2012). It has not been identified in large populat ion studies. This variant is predicted to cause a frameshift, which alters the p rotein?s amino acid sequence beginning at position 4458 and leads to a premature termination codon 3 amino acids downstream. This alteration is then predicted t o lead to a truncated or absent protein. In summary, this variant meets our crit eria to be classified as pathogenic for usher syndrome in an autosomal recessive manner (www.partners.org/personalizedmedicine/lmm).
