Genetic Variant NRIP2:p.Gly259Glu (chr12-2827277-C-T) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

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

The NM_031474.3(NRIP2):c.776G>A(p.Gly259Glu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000342 in 1,461,646 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/20 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. G259R) has been classified as Uncertain significance.

The c.776G>A (p.G259E) alteration is located in exon 6 (coding exon 6) of the NRIP2 gene. This alteration results from a G to A substitution at nucleotide position 776, causing the glycine (G) at amino acid position 259 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
