Variant 8-63038752-C-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_003878.3(GGH):c.17G>A(p.Cys6Tyr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000636 in 1,572,256 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C6R) has been classified as Likely benign.

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]

Ambry Genetics

Apr 10, 2023

The c.17G>A (p.C6Y) alteration is located in exon 1 (coding exon 1) of the GGH gene. This alteration results from a G to A substitution at nucleotide position 17, causing the cysteine (C) at amino acid position 6 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
