RCV000483731 | SCV000569802 | likely pathogenic | not provided | 2016-04-11 | criteria provided, single submitter | clinical testing | A novel c.2102delG variant that is likely pathogenic has been identified in the ATP1A2 gene. The c.2102delG variant causes a frameshift starting with codon Glycine 701, changes this amino acid to an Aspartic acid residue and creates a premature Stop codon at position 11 of the new reading frame, denoted p.Gly701AspfsX11. This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. It was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Although this variant has not been previously reported to our knowledge, other downstream loss-of-function variants have been reported in the Human Gene Mutation Database in association with ATP1A2-related disorders (Stenson et al., 2014). Therefore, this variant is likely pathogenic; however, the possibility that it is benign cannot be excluded. |
