Variant summary
Our verdict is Benign. The variant received -8 ACMG points: 0P and 8B. BP4_StrongBS2
The NM_021930.6(RINT1):c.767G>C(p.Arg256Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000353 in 1,614,114 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/22 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. R256Q) has been classified as Likely benign.

not specified Uncertain:1
The p.R256P variant (also known as c.767G>C), located in coding exon 6 of the RINT1 gene, results from a G to C substitution at nucleotide position 767. The arginine at codon 256 is replaced by proline, an amino acid with dissimilar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
not provided Uncertain:1
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. ClinVar contains an entry for this variant (Variation ID: 843043). This variant has not been reported in the literature in individuals affected with RINT1-related conditions. This variant is present in population databases (rs199512216, gnomAD 0.02%), including at least one homozygous and/or hemizygous individual. This sequence change replaces arginine, which is basic and polar, with proline, which is neutral and non-polar, at codon 256 of the RINT1 protein (p.Arg256Pro).
