RCV000484212 | SCV000571580 | likely pathogenic | not provided | 2016-09-15 | criteria provided, single submitter | clinical testing | A novel c.2096dupC variant that is likely pathogenic has been identified in the CNTNAP2 gene. The c.2096dupC 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.2096dupC variant in the CNTNAP2 gene causes a frameshift starting with codon Aspartic acid 700, changes this amino acid to an Arginine residue and creates a premature Stop codon at position 45 of the new reading frame, denoted p.Asp700ArgfsX45. The c.2096dupC variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. Although this likely pathogenic variant has not been previously reported to our knowledge, other loss of function variants have been reported downstream of the c.2096dupC variant. Therefore, this variant is likely pathogenic; however, the possibility that it is benign cannot be excluded. |
