Collection Method: clinical testing

The c.877G>A (p.G293S) alteration is located in exon 8 (coding exon 7) of the RASGEF1C gene. This alteration results from a G to A substitution at nucleotide position 877, causing the glycine (G) at amino acid position 293 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
