Comment:

NM_004006.2(DMD):c.3184A>T(K1062*) is expected to be pathogenic in the context of dystrophinopathy (including Duchenne/Becker muscular dystrophy). This variant is predicted to lead to an abnormal or absent protein product due to the creation of a premature termination codon in DMD, a gene where loss-of-function variants are known to be pathogenic. Please note: this variant was assessed in the context of healthy population screening.

Comment:

This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Lys1062*) in the DMD gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DMD are known to be pathogenic (PMID: 16770791, 25007885). This variant has not been reported in the literature in individuals affected with DMD-related conditions. For these reasons, this variant has been classified as Pathogenic.
