RCV000311228 | SCV000330474 | pathogenic | not provided | 2016-05-13 | criteria provided, single submitter | clinical testing | The c.191_207dup17 pathogenic variant in the PRRT2 gene causes a frameshift starting with codon Glutamic acid 70, changes this amino acid to a Arginine residue and creates a premature Stop codon at position 26 of the new reading frame, denoted p.E70RfsX26. This pathogenic 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 pathogenic variant has not been previously reported to our knowledge, other frameshift variants have been reported in Human Gene Mutation Database in association with PRRT2-related disorders (Stenson et al., 2014). |
