not provided Uncertain:1
This variant is present in population databases (rs759986717, gnomAD 0.04%). 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 affected with CHRNA3-related conditions. This sequence change creates a premature translational stop signal (p.Leu499*) in the CHRNA3 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 7 amino acid(s) of the CHRNA3 protein. -
