Description

The p.I879V variant (also known as c.2635A>G), located in coding exon 25 of the RB1 gene, results from an A to G substitution at nucleotide position 2635. The isoleucine at codon 879 is replaced by valine, an amino acid with highly similar properties. This amino acid position is conserved. 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.
