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]

5-Oxoprolinase deficiency Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpMar 16, 2018This sequence change creates a premature translational stop signal (p.Arg853*) in the OPLAH gene. It is expected to result in an absent or disrupted protein product. This variant is present in population databases (rs543486699, ExAC 0.01%). This variant has not been reported in the literature in individuals with OPLAH-related disease. Loss-of-function variants in OPLAH are known to be pathogenic (PMID: 21651516). For these reasons, this variant has been classified as Pathogenic. -
