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]

FAM98A (HGNC:24520): (family with sequence similarity 98 member A) Enables protein methyltransferase activity. Involved in positive regulation of cell population proliferation; positive regulation of gene expression; and protein methylation. Predicted to be part of tRNA-splicing ligase complex.

The c.1931C>T (p.A644V) alteration is located in exon 17 (coding exon 15) of the RASGRP3 gene. This alteration results from a C to T substitution at nucleotide position 1931, causing the alanine (A) at amino acid position 644 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
