Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the LIPA gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Crucial for the intracellular hydrolysis of cholesteryl esters and triglycerides that have been internalized via receptor- mediated endocytosis of lipoprotein particles. Important in mediating the effect of LDL (low density lipoprotein) uptake on suppression of hydroxymethylglutaryl-CoA reductase and activation of endogenous cellular cholesteryl ester formation.
• Disease: DISEASE: Wolman disease (WOD) [MIM:278000]: A severe manifestation of LIPA deficiency, leading to the accumulation of cholesteryl esters and triglycerides in most tissues of the body. WD occurs in infancy and is nearly always fatal before the age of 1 year. {ECO:0000269|PubMed:8146180}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Cholesteryl ester storage disease (CESD) [MIM:278000]: A mild manifestation of LIPA deficiency, leading to the accumulation of cholesteryl esters and triglycerides in most tissues of the body. It is characterized by late-onset. {ECO:0000269|PubMed:8146180, ECO:0000269|PubMed:9633819}. Note=The disease is caused by mutations affecting the gene represented in this entry.
