Genes affected
LPL (HGNC:6677): (lipoprotein lipase) LPL encodes lipoprotein lipase, which is expressed in heart, muscle, and adipose tissue. LPL functions as a homodimer, and has the dual functions of triglyceride hydrolase and ligand/bridging factor for receptor-mediated lipoprotein uptake. Severe mutations that cause LPL deficiency result in type I hyperlipoproteinemia, while less extreme mutations in LPL are linked to many disorders of lipoprotein metabolism.

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 19, 2023This sequence change creates a premature translational stop signal (p.Gln133*) in the LPL gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in LPL are known to be pathogenic (PMID: 11334614). This variant is present in population databases (rs118204058, gnomAD 0.0009%). This premature translational stop signal has been observed in individual(s) with clinical features of familial chylomicronemia syndrome (PMID: 2349938). This variant is also known as p.Gln106*. For these reasons, this variant has been classified as Pathogenic. -
