RCV001030431 | SCV001189950 | pathogenic | Alagille syndrome due to a JAG1 point mutation | 2020-02-26 | criteria provided, single submitter | clinical testing | The c.1377_1378del variant is not present in publicly available databases like 1000 Genomes, Exome Variant Server (EVS), Exome Aggregation Consortium (ExAC), Genome Aggregation Database (gnomAD) and dbSNP. The variant is not present in our in-house exome database. The variant was not reported earlier to OMIM, ClinVar or HGMD databases. The variant causes a frameshift at 459th amino acid position that creates stop codon at 460th amino acid position. This may either cause nonsense mediated decay of the mRNA resulting no protein or a truncated protein due to premature stop codon. In-silico pathogenicity prediction programs MutationTaster2, CADD, Intervar etc. predicted this variant to be likely deleterious. The variant has been classified as pathogenic as per ACMG guidelines. |
