Variant chr1-156077158-C-T 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_001093725.2(MEX3A):c.979G>A(p.Gly327Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000186 in 1,613,406 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. G327V) has been classified as Uncertain significance.

The c.979G>A (p.G327S) alteration is located in exon 2 (coding exon 2) of the MEX3A gene. This alteration results from a G to A substitution at nucleotide position 979, causing the glycine (G) at amino acid position 327 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
