Test Description

PMC Congenital Muscular Dystrophy Panel examines genes linked to a range of neuromuscular conditions known as congenital muscular dystrophies. Due to overlapping clinical features of hereditary susceptibility conditions| utilizing a comprehensive panel test enables a thorough evaluation of potential genes for individuals with similar clinical symptoms. Some genes included in this panel may also be associated with conditions unrelated to the clinical indication for testing.

Genetic testing can help with establishing accurate diagnosis| targeted treatment| prognosis prediction| family planning and preventive measures.

  • Associated Conditions
    • Congenital Muscular Dystrophy
    • Dystroglycanopathies
    • muscular dystrophy-dystroglycanopathy type A1 (MDDGA1), type B1 (MDDGB1), type C1 (MDDGC1)
    • muscular dystrophy-dystroglycanopathy type A10 (MDDGA10)
    • muscular dystrophy-dystroglycanopathy type A11 (MDDGA11)
    • muscular dystrophy-dystroglycanopathy type A12 (MDDGA12), type C12 (MDDGC12)
    • muscular dystrophy-dystroglycanopathy type A13 (MDDGA13)
  • Methodology

    Targeted Exome/ Slice Exome (Next Generation Sequencing including Copy Number Variation)

  • Assay Information
    • DMD: Analysis guarantees del/dup detection at single-exon resolution.
    • FKTN: Analysis includes the intronic variant NM_001079802.1:c.647+2084G>T (also known as NM_001079802.1:c.648-1243G>T) and the ~3 kb retrotransposon insertion in the 3' UTR at position NM_001079802‚Äã.1:c.*4392_*4393.
  • Limitations

    All sequencing technologies have limitations. A negative result from this analysis does not rule out a possible genetic diagnosis as some variants may not be detected by this test. This test is not designed to detect low level mosaicism, structural rearrangements, indels >40bp, deep intronic variants of unknown clinical significance, or large cytogenetic CNVs. Certain inherent qualities of the human genome, for example repetitive regions/homopolymers, GC rich, pseudogenes, and rare polymorphisms, pose significant technical challenges such as sequence misalignment that may potentially impact the accuracy of the results. False negative results may also occur in the setting of allogeneic bone marrow, stem cell transplantation, active or chronic hematologic conditions, recent blood transfusions, suboptimal DNA quality or PCR trace contamination. Other potential sources of error include sample mix-ups and clerical issues.
