GeneDx RCV000188396 SCV000242008 pathogenic not provided 2013-02-26 criteria provided, single submitter clinical testing This variant is denoted c.1958_1959dupCT: p.Ala654LeufsX7 (A654Lfsx7) in exon 1 of the PCDH19 gene (NM_001105243.1). The c.1958_1959dupCT mutation in the PCDH19 gene causes a frameshift starting with codon Alanine 654, changes this amino acid to a Leucine residue and creates a premature Stop codon at position 7 of the new reading frame, denoted p.Ala654LeufsX7. This mutation is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. Although this mutation has not been previously reported to our knowledge, other frameshift mutations in this gene have been reported in association with epilepsy. Therefore, the presence of c.1958_1959dupCT is consistent with a diagnosis of a PCDH19-related disorder. The variant is found in EPILEPSY panel(s).
