Therefore, it has been classified as a Variant of Uncertain Significance. 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 not expected to disrupt CYP4V2 protein function. This variant has been observed in individual(s) with Bietti crystalline dystrophy (external communication). ClinVar contains an entry for this variant (Variation ID: 866106). This variant is present in population databases (rs778598903, ExAC 0.01%). This sequence change replaces leucine with proline at codon 65 of the CYP4V2 protein (p.Leu65Pro). The leucine residue is weakly conserved and there is a moderate physicochemical difference between leucine and proline. |
