Description

This sequence change affects the initiator methionine of the TBC1D24 mRNA. The next in-frame methionine is located at codon 15. 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. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. ClinVar contains an entry for this variant (Variation ID: 1062856). This variant has not been reported in the literature in individuals affected with TBC1D24-related conditions. This variant is not present in population databases (gnomAD no frequency).
