Genes affected

LIPA (HGNC:6617): (lipase A, lysosomal acid type) This gene encodes lipase A, the lysosomal acid lipase (also known as cholesterol ester hydrolase). This enzyme functions in the lysosome to catalyze the hydrolysis of cholesteryl esters and triglycerides. Mutations in this gene can result in Wolman disease and cholesteryl ester storage disease. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jan 2014]

This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 357 of the LIPA protein (p.Leu357Pro). This variant is present in population databases (rs772684869, gnomAD 0.008%). This missense change has been observed in individual(s) with cholesteryl ester storage disease (PMID: 7773732). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is also known as Leu336Pro. ClinVar contains an entry for this variant (Variation ID: 552474). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt LIPA protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects LIPA function (PMID: 7499245, 31131398, 31180157). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -
