Invitae RCV001858536 SCV002115429 uncertain significance Wolman disease 2022-08-15 criteria provided, single submitter clinical testing This sequence change replaces asparagine, which is neutral and polar, with aspartic acid, which is acidic and polar, at codon 123 of the LIPA protein (p.Asn123Asp). This variant is present in population databases (rs771904218, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with LIPA-related conditions. ClinVar contains an entry for this variant (Variation ID: 695058). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C15"). Experimental studies have shown that this missense change affects LIPA function (PMID: 31180157). 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.
