This variant has not been reported in the literature in individuals affected with PUS1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.01%). This sequence change creates a premature translational stop signal (p.Lys306*) in the PUS1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PUS1 are known to be pathogenic (PMID: 17056637, 19731322, 25058219, 26556812). (less)
