Variant 8-144051373-C-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Benign. Variant got -8 ACMG points: 2P and 10B. PM2BP4_StrongBP6_ModerateBS1

The ENST00000618853.5(OPLAH):c.3820G>A(p.Glu1274Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000108 in 1,607,068 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 10/16 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E1274V) has been classified as Likely benign.

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]
