RCV000188393 | SCV000242005 | pathogenic | not provided | 2014-04-30 | criteria provided, single submitter | clinical testing | This variant is denoted c.1683_1696delGGTCATCACAGCCC: p.Val562ThrfsX4 (V562TfsX4) in exon 1 of the PCDH19 gene (NM_001105243.1). The normal sequence with the bases that are deleted in braces is: ACCCC{GGTCATCACAGCCC}CACC. The c.1683_1696delGGTCATCACAGCCC mutation in the PCDH19 gene causes a frameshift starting with codon Valine 562, changes this amino acid to a Threonine residue and creates a premature Stop codon at position 14 of the new reading frame, denoted p.Val562ThrfsX4. 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 the PCDH19 gene have been published in association with epilepsy. The variant is found in INFANT-EPI panel(s). |
