Description

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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. This variant has not been reported in the literature in individuals affected with TTR-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change falls in intron 1 of the TTR gene. It does not directly change the encoded amino acid sequence of the TTR protein.
