Description

This sequence change falls in intron 12 of the RPE65 gene. It does not directly change the encoded amino acid sequence of the RPE65 protein. This variant is present in population databases (rs746665921, gnomAD 0.005%). This variant has been observed in individual(s) with RPE65-related conditions (Invitae). ClinVar contains an entry for this variant (Variation ID: 935854). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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.
