Genetic Variant RIMBP3B:p.Gly1512Glu (chr22-21388393-G-A) – ACMG Classification: Likely_benign (-1 pts)

Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 0P and 1B. BP4

The NM_001128635.2(RIMBP3B):c.4535G>A(p.Gly1512Glu) variant causes a missense change involving the alteration of a non-conserved nucleotide. In-silico tool predicts a benign outcome for this variant. 11/17 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. G1512R) has been classified as Uncertain significance.

The c.4535G>A (p.G1512E) alteration is located in exon 1 (coding exon 1) of the RIMBP3B gene. This alteration results from a G to A substitution at nucleotide position 4535, causing the glycine (G) at amino acid position 1512 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
