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]

The c.1262T>C (p.I421T) alteration is located in exon 9 (coding exon 9) of the LIPI gene. This alteration results from a T to C substitution at nucleotide position 1262, causing the isoleucine (I) at amino acid position 421 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
