Description

For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with CCDC39-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Gln221Argfs*4) in the CCDC39 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CCDC39 are known to be pathogenic (PMID: 21131972, 23255504).
