RCDP is a peroxisomal disorder caused by mutations in ether lipid (plasmalogen) biosynthesis-associated genes such as alkylglycerone-phosphate synthase (AGPS), glycerol-3-phosphate acyltransferase (GNPAT), and fatty acyl-CoA reductase 1 enzyme (FAR1) [90,91]. Here, AGPS is linked to peroxisomal disease.
