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 disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has been observed in individual(s) with cone rod dystrophy or retinitis pigmentosa (PMID: 26355662, Invitae). ClinVar contains an entry for this variant (Variation ID: 191106). This variant is not present in population databases (ExAC no frequency). This sequence change replaces alanine with threonine at codon 92 of the CRX protein (p.Ala92Thr). The alanine residue is highly conserved and there is a small physicochemical difference between alanine and threonine.
