Genes affected
OPLAH (HGNC:8149): (5-oxoprolinase, ATP-hydrolysing) The protein encoded by this gene acts as a homodimer, using ATP hydrolysis to catalyze the conversion of 5-oxo-L-proline to L-glutamate. Defects in this gene are a cause of 5-oxoprolinase deficiency (OPLAHD). [provided by RefSeq, Jun 2012]
SMPD5 (HGNC:52275): (sphingomyelin phosphodiesterase 5 (pseudogene)) Predicted to enable sphingomyelin phosphodiesterase activity. Predicted to be involved in ceramide biosynthetic process and sphingomyelin catabolic process. Predicted to act upstream of or within ceramide metabolic process. Predicted to be located in endoplasmic reticulum membrane and mitochondrial membrane. [provided by Alliance of Genome Resources, Apr 2022]
