Genes affected
PLA2G4D (HGNC:30038): (phospholipase A2 group IVD) The phospholipase A2 enzyme family, including PLA2G4D, catalyze the hydrolysis of glycerophospholipids at the sn-2 position and then liberate free fatty acids and lysophospholipids (Chiba et al., 2004 [PubMed 14709560]).[supplied by OMIM, Jun 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 17, 2023The c.1990C>T (p.R664C) alteration is located in exon 18 (coding exon 18) of the PLA2G4D gene. This alteration results from a C to T substitution at nucleotide position 1990, causing the arginine (R) at amino acid position 664 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
