RCV000493356 | SCV000583237 | pathogenic | not provided | 2017-05-30 | criteria provided, single submitter | clinical testing | The c.648dupC pathogenic variant in the JAG1 gene causes a frameshift starting with codon Asparagine 217, changes this amino acid to a Glutamine residue and creates a premature Stop codon at position 14 of the new reading frame, denoted p.Asn217GlnfsX14. This pathogenic variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The c.648dupC variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). Although this pathogenic variant has not been previously reported to our knowledge, its presence is consistent with the diagnosis of Alagille syndrome. |
