Description

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 1454233). This variant has not been reported in the literature in individuals affected with SMAD3-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Asn24Lysfs*89) in the SMAD3 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SMAD3 are known to be pathogenic (PMID: 21778426, 24804794).
