Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2PP2PP3

The NM_000235.4(LIPA):​c.683T>G​(p.Phe228Cys) variant causes a missense change. The variant allele was found at a frequency of 0.00000682 in 1,614,002 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. F228S) has been classified as Uncertain significance.

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]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 39 curated pathogenic missense variants (we use a threshold of 10). The gene has 5 curated benign missense variants. Gene score misZ: 0.22832 (below the threshold of 3.09). Trascript score misZ: 0.63421 (below the threshold of 3.09). GenCC associations: The gene is linked to cholesteryl ester storage disease, lysosomal acid lipase deficiency, Wolman disease.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.792
