Description

For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with DNAJC21-related conditions. This variant is present in population databases (rs777941059, gnomAD 0.0009%). This sequence change creates a premature translational stop signal (p.Lys105Argfs*13) in the DNAJC21 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DNAJC21 are known to be pathogenic (PMID: 27346687, 28062395).
