Genes affected

ARHGEF40 (HGNC:25516): (Rho guanine nucleotide exchange factor 40) This gene encodes a protein similar to guanosine nucleotide exchange factors for Rho GTPases. The encoded protein contains in its C-terminus a GEF domain involved in exchange activity and a pleckstrin homology domain. Alternatively spliced transcripts that encode different proteins have been described. [provided by RefSeq, Mar 2014]

Ambry Genetics

Dec 19, 2022

The c.919G>A (p.G307S) alteration is located in exon 3 (coding exon 3) of the ARHGEF40 gene. This alteration results from a G to A substitution at nucleotide position 919, causing the glycine (G) at amino acid position 307 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
