Genes affected

PLA2G12B (HGNC:18555): (phospholipase A2 group XIIB) The protein encoded by this gene belongs to the phospholipase A2 (PLA2) group of enzymes, which function in glycolipid hydrolysis with the release of free fatty acids and lysophospholipids. This family member has altered phospholipid-binding properties and is catalytically inactive. The protein is secreted, and together with microsomal triglyceride transfer protein, it functions to regulate HNF4alpha-induced hepatitis C virus infectivity. The expression of this gene is down-regulated in various tumors, suggesting that it may function as a negative regulator of tumor progression. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Dec 2015]

Dec 13, 2022

The c.292C>T (p.P98S) alteration is located in exon 2 (coding exon 2) of the PLA2G12B gene. This alteration results from a C to T substitution at nucleotide position 292, causing the proline (P) at amino acid position 98 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
