Variant 6-32192157-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_001276501.2(GPSM3):c.136C>T(p.Arg46Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000737 in 1,357,294 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/20 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. R46H) has been classified as Likely benign.

The c.136C>T (p.R46C) alteration is located in exon 6 (coding exon 2) of the GPSM3 gene. This alteration results from a C to T substitution at nucleotide position 136, causing the arginine (R) at amino acid position 46 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
