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

Sep 01, 2021

The c.521T>A (p.F174Y) alteration is located in exon 5 (coding exon 5) of the RND2 gene. This alteration results from a T to A substitution at nucleotide position 521, causing the phenylalanine (F) at amino acid position 174 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
