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

Our verdict: Pathogenic. The variant received 11 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr10-89215004-C-G is described in ClinVar as Pathogenic. ClinVar VariationId is 1350454.Status of the report is criteria_provided_single_submitter, 1 stars.
• 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, 0.993
• PP5: Variant 10-89215004-C-A is Pathogenic according to our data. Variant chr10-89215004-C-A is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 695041.Status of the report is criteria_provided_single_submitter, 1 stars.
