Genes affected

LIPI (HGNC:18821): (lipase I) The protein encoded by this gene is a phospholipase that hydrolyzes phosphatidic acid to produce lysophosphatidic acid. Defects in this gene are a cause of susceptibility to familial hypertrigliceridemia. This gene is also expressed at high levels in Ewing family tumor cells. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2014]

This variant is not present in population databases (ExAC no frequency). This sequence change replaces lysine with asparagine at codon 379 of the LIPI protein (p.Lys379Asn). The lysine residue is moderately conserved and there is a moderate physicochemical difference between lysine and asparagine. This variant has not been reported in the literature in individuals affected with LIPI-related conditions. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). -
