Variant 17-43028616-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_005440.5(RND2):c.620G>A(p.Arg207Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000685 in 1,460,156 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. R207W) has been classified as Uncertain significance.

Genes affected

RND2 (HGNC:18315): (Rho family GTPase 2) This gene encodes a member of the Rho GTPase family, whose members play a key role in the regulation of actin cytoskeleton organization in response to extracellular growth factors. This particular family member has been implicated in the regulation of neuronal morphology and endosomal trafficking. The gene localizes to chromosome 17 and is the centromeric neighbor of the breast-ovarian cancer susceptibility gene BRCA1. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 06, 2022

The c.620G>A (p.R207Q) alteration is located in exon 5 (coding exon 5) of the RND2 gene. This alteration results from a G to A substitution at nucleotide position 620, causing the arginine (R) at amino acid position 207 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
