Labcorp Genetics (formerly Invitae), Labcorp RCV002588405 SCV003494469 uncertain significance Hypoplastic left heart syndrome 2023-07-14 criteria provided, single submitter clinical testing This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 103 of the HAND1 protein (p.Glu103Gly). This variant has not been reported in the literature in individuals affected with HAND1-related conditions. ClinVar contains an entry for this variant (Variation ID: 2177881). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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.
