GeneDx RCV000370765 SCV000330707 pathogenic not provided 2016-08-10 criteria provided, single submitter clinical testing The c.2179_2180dupTC pathogenic variant in the POMT1 gene causes a frameshift starting with codon Proline 728, changes this amino acid to an Arginine residue and creates a premature Stop codon at position 17 of the new reading frame, denoted p.Pro728ArgfsX17. This pathogenic variant is predicted to cause loss of normal protein function through protein truncation, as the last 20 amino acids are replaced with 16 incorrect amino acids. Furthermore, c.2179_2180dupTC 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 reported previously to our knowledge, other frameshift variants have been reported in the Human Gene Mutation Database in association with POMT1-related disorders (Stenson et al., 2014). Therefore, c.2179_2180dupTC is considered a pathogenic variant.
