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 GeneticsOct 06, 2021The c.2072G>A (p.R691Q) alteration is located in exon 19 (coding exon 19) of the PLA2G4D gene. This alteration results from a G to A substitution at nucleotide position 2072, causing the arginine (R) at amino acid position 691 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
