Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4_ModerateBS2

The NM_001093725.2(MEX3A):c.980G>T(p.Gly327Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000452 in 1,613,388 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 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. G327S) has been classified as Uncertain significance.

The c.980G>T (p.G327V) alteration is located in exon 2 (coding exon 2) of the MEX3A gene. This alteration results from a G to T substitution at nucleotide position 980, causing the glycine (G) at amino acid position 327 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
