Description

This sequence change affects codon 434 of the SLC6A8 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the SLC6A8 protein. This variant is present in population databases (no rsID available, gnomAD 0.001%). This variant has not been reported in the literature in individuals affected with SLC6A8-related conditions. ClinVar contains an entry for this variant (Variation ID: 571476). 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.
