Description

This sequence change creates a premature translational stop signal (p.Leu450*) in the PPM1D gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 156 amino acid(s) of the PPM1D protein. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with PPM1D-related conditions. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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.
