Variant summary
Our verdict is Pathogenic. The variant received 15 ACMG points: 15P and 0B. PM2PP2PP3_StrongPP5_Very_Strong
The NM_000235.4(LIPA):c.1070T>C(p.Leu357Pro) variant causes a missense change. The variant allele was found at a frequency of 0.0000118 in 1,614,048 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. L357L) has been classified as Likely benign.

Wolman disease Pathogenic:1
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. -
