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]

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

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. For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Gly342 amino acid residue in LIPA. Other variant(s) that disrupt this residue have been observed in individuals with LIPA-related conditions (PMID: 9925650), which suggests that this may be a clinically significant amino acid residue. Experimental studies have shown that this missense change affects LIPA function (PMID: 10562460). ClinVar contains an entry for this variant (Variation ID: 555337). This missense change has been observed in individuals with LIPA-related conditions (PMID: 10562460, 23485521, 24048164, 28881270). This variant is present in population databases (rs776472526, gnomAD 0.003%). This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 342 of the LIPA protein (p.Gly342Arg). -
