Genes affected

LIPH (HGNC:18483): (lipase H) This gene encodes a membrane-bound member of the mammalian triglyceride lipase family. It catalyzes the production of 2-acyl lysophosphatidic acid (LPA), which is a lipid mediator with diverse biological properties that include platelet aggregation, smooth muscle contraction, and stimulation of cell proliferation and motility.

The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.009%). Predicted Consequence/Location: Missense variant In silico tool predictions suggest damaging effect of the variant on gene or gene product [REVEL: 0.92 (>=0.6, sensitivity 0.68 and specificity 0.92); 3Cnet: 0.96 (>=0.6, sensitivity 0.72 and precision 0.9)]. Same nucleotide change resulting in same amino acid change has been previously reported to be associated with LIPH related disorder (ClinVar ID: VCV000030669 /PMID: 19892526). The variant has been reported to be in trans with a pathogenic variant as either compound heterozygous or homozygous in at least one similarly affected unrelated individual (PMID: 19892526). Therefore, this variant is classified as Likely pathogenic according to the recommendation of ACMG/AMP guideline. -
