Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_175062.4(RASGEF1C):c.650G>A(p.Arg217Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000322 in 1,612,822 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R217W) has been classified as Uncertain significance.

Collection Method: clinical testing

The c.650G>A (p.R217Q) alteration is located in exon 6 (coding exon 5) of the RASGEF1C gene. This alteration results from a G to A substitution at nucleotide position 650, causing the arginine (R) at amino acid position 217 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
