Genes affected

RASGRP3 (HGNC:14545): (RAS guanyl releasing protein 3) The protein encoded by this gene is a guanine nucleotide exchange factor that activates the oncogenes HRAS and RAP1A. Defects in this gene have been associated with systemic lupus erythematosus and several cancers. [provided by RefSeq, Mar 2017]

Dec 27, 2023

The c.169T>G (p.C57G) alteration is located in exon 4 (coding exon 2) of the RASGRP3 gene. This alteration results from a T to G substitution at nucleotide position 169, causing the cysteine (C) at amino acid position 57 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
