This sequence change affects codon 54 of the DTNBP1 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the DTNBP1 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs77460377, gnomAD 0.1%), and has an allele count higher than expected for a pathogenic variant. This variant has not been reported in the literature in individuals affected with DTNBP1-related conditions. ClinVar contains an entry for this variant (Variation ID: 210857). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. 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.
