Genes affected

GGH (HGNC:4248): (gamma-glutamyl hydrolase) This gene catalyzes the hydrolysis of folylpoly-gamma-glutamates and antifolylpoly-gamma-glutamates by the removal of gamma-linked polyglutamates and glutamate. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.004662961).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.258 is higher than 0.05.
