Description

This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 2033 of the CEP290 protein (p.Glu2033Gly). This variant is present in population databases (rs756608200, gnomAD 0.0009%). This missense change has been observed in individual(s) with retinitis pigmentosa (Invitae). ClinVar contains an entry for this variant (Variation ID: 806917). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt CEP290 protein function with a positive predictive value of 80%. 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.
