EGL Genetic Diagnostics, Eurofins Clinical Diagnostics RCV000727161 SCV000706223 uncertain significance not provided 2017-02-02 criteria provided, single submitter clinical testing
GeneDx RCV000593468 SCV000726108 likely benign not specified 2018-01-22 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.
Invitae RCV001208418 SCV001379805 uncertain significance Alagille syndrome 1 2020-09-04 criteria provided, single submitter clinical testing This sequence change replaces arginine with histidine at codon 543 of the JAG1 protein (p.Arg543His). The arginine residue is moderately conserved and there is a small physicochemical difference between arginine and histidine. This variant is present in population databases (rs544877858, ExAC 0.07%), and has an allele count higher than expected for a pathogenic variant (PMID: 28166811). This variant has not been reported in the literature in individuals with JAG1-related conditions. ClinVar contains an entry for this variant (Variation ID: 500328). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
