| Invitae | RCV000537741 | SCV000629323 | uncertain significance | Retinoblastoma | 2017-07-03 | criteria provided, single submitter | clinical testing | This variant has not been reported in the literature in individuals with RB1-related disease. 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant is not present in population databases (ExAC no frequency). This sequence change replaces isoleucine with methionine at codon 92 of the RB1 protein (p.Ile92Met). The isoleucine residue is weakly conserved and there is a small physicochemical difference between isoleucine and methionine. |
