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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 25, 2023The c.845G>A (p.R282H) 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 845, causing the arginine (R) at amino acid position 282 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
