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. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. This variant has not been reported in the literature in individuals with SDHB-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change results in a premature translational stop signal in the SDHB gene (p.Ile263Metfs*7). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 18 amino acids of the SDHB protein.
