Description

This sequence change creates a premature translational stop signal (p.Trp522*) in the DHTKD1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DHTKD1 are known to be pathogenic (PMID: 23141293, 25860818). For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with DHTKD1-related conditions. This variant is not present in population databases (gnomAD no frequency).
