GeneDx RCV000481295 SCV000569996 likely pathogenic not provided 2016-04-18 criteria provided, single submitter clinical testing A novel c.1189_1237dup49 variant that is likely pathogenic has been identified in the PNKP gene. The c.1189_1237dup49 variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. 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. The c.1189_1237dup49 variant causes a frameshift starting with codon Leucine 413, changes this amino acid to an Arginine residue and creates a premature Stop codon at position 14 of the new reading frame, denoted p.Leu413ArgfsX14. This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. Therefore, this variant is likely pathogenic; however, the possibility that it is benign cannot be excluded.
