Description

ClinVar contains an entry for this variant (Variation ID: 1303133). This variant has not been reported in the literature in individuals affected with PRODH-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change creates a premature translational stop signal (p.Gln526*) in the PRODH gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 75 amino acid(s) of the PRODH protein. 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.
