Genes affected

ARHGEF7 (HGNC:15607): (Rho guanine nucleotide exchange factor 7) This gene encodes a protein that belongs to a family of cytoplasmic proteins that activate the Ras-like family of Rho proteins by exchanging bound GDP for GTP. It forms a complex with the small GTP binding protein Rac1 and recruits Rac1 to membrane ruffles and to focal adhesions. Multiple alternatively spliced transcript variants encoding different isoforms have been observed for this gene. [provided by RefSeq, Mar 2016]

The c.644G>A (p.R215H) alteration is located in exon 6 (coding exon 6) of the ARHGEF7 gene. This alteration results from a G to A substitution at nucleotide position 644, causing the arginine (R) at amino acid position 215 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
