Variant summary
Our verdict is Likely pathogenic. The variant received 9 ACMG points: 9P and 0B. PM1PM5PP2PP3_Strong
The NM_000539.3(RHO):c.404G>A(p.Arg135Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000681 in 1,614,118 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. R135L) has been classified as Pathogenic.

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant disrupts the p.Arg135 amino acid residue in RHO. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 1862076, 18175313). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. This variant has been reported to have conflicting or insufficient data to determine the effect on RHO protein function (PMID: 9538004, 2573063, 8099498). This variant has not been reported in the literature in individuals with RHO-related conditions. This variant is present in population databases (rs104893774, ExAC 0.001%). This sequence change replaces arginine with glutamine at codon 135 of the RHO protein (p.Arg135Gln). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and glutamine. -
