Variant summary
Our verdict is Likely benign. Variant got -4 ACMG points: 0P and 4B. BS2
The NM_000978.4(RPL23):c.265C>G(p.Arg89Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000143 in 1,613,684 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. R89H) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Apr 14, 2023 | 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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant  is likely to be tolerated. This variant has not been reported in the literature in individuals affected with RPL23-related conditions. This variant is present in population databases (rs770495795, gnomAD 0.02%). This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 89 of the RPL23 protein (p.Arg89Gly). - |
