Genetic Variant RHOF:p.Arg201Gln (chr12-121779532-C-T) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

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

The NM_019034.3(RHOF):c.602G>A(p.Arg201Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000124 in 1,612,904 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 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. R201W) has been classified as Uncertain significance.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.602G>A (p.R201Q) alteration is located in exon 5 (coding exon 5) of the RHOF gene. This alteration results from a G to A substitution at nucleotide position 602, causing the arginine (R) at amino acid position 201 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
