Genes affected

ARHGEF33 (HGNC:37252): (Rho guanine nucleotide exchange factor 33) Predicted to enable guanyl-nucleotide exchange factor activity. Predicted to be involved in regulation of catalytic activity. [provided by Alliance of Genome Resources, Apr 2022]

ARHGEF33 links:

SOS1 (HGNC:11187): (SOS Ras/Rac guanine nucleotide exchange factor 1) This gene encodes a protein that is a guanine nucleotide exchange factor for RAS proteins, membrane proteins that bind guanine nucleotides and participate in signal transduction pathways. GTP binding activates and GTP hydrolysis inactivates RAS proteins. The product of this gene may regulate RAS proteins by facilitating the exchange of GTP for GDP. Mutations in this gene are associated with gingival fibromatosis 1 and Noonan syndrome type 4. [provided by RefSeq, Jul 2008]

The c.2429G>C (p.R810T) alteration is located in exon 15 (coding exon 15) of the ARHGEF33 gene. This alteration results from a G to C substitution at nucleotide position 2429, causing the arginine (R) at amino acid position 810 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
