RCV000188391 | SCV000242003 | pathogenic | not provided | 2012-10-31 | criteria provided, single submitter | clinical testing | This variant is denoted c.1134delA: p.Gly379AlafsX190 (G379AfsX190) in exon 1 of the PCDH19 gene (NM_001105243.1). The normal sequence with the base that is deleted in braces is: ACTC{A}GGCCT. The c.1134delA mutation in the PCDH19 gene causes a frameshift starting with codon Glycine 379, changes this amino acid to an Alanine residue and creates a premature Stop codon at position 190 of the new reading frame, denoted p.Gly379AlafsX190. 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, many other frameshift mutations have been reported in the PCDH19 gene. Therefore, the presence of c.1134delA is consistent with a diagnosis of a PCDH19-related disorder. The variant is found in EPILEPSY panel(s). |
