Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The ENST00000312295.5(RTP1):c.505C>G(p.Arg169Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000583 in 1,612,956 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. R169H) has been classified as Uncertain significance.

Ambry Genetics

Apr 19, 2023

The c.505C>G (p.R169G) alteration is located in exon 2 (coding exon 2) of the RTP1 gene. This alteration results from a C to G substitution at nucleotide position 505, causing the arginine (R) at amino acid position 169 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
