Variant 1-26894400-C-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_022078.3(GPATCH3):c.887G>T(p.Arg296Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000304 in 1,613,816 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. R296G) has been classified as Uncertain significance.

Ambry Genetics

May 03, 2023

The c.887G>T (p.R296L) alteration is located in exon 3 (coding exon 3) of the GPATCH3 gene. This alteration results from a G to T substitution at nucleotide position 887, causing the arginine (R) at amino acid position 296 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
