Rhabdomyolysis: Sequencing Panel

Create a PDF of this page

Condition Description

Rhabdomyolysis is caused by the breakdown of muscle leading to an increase in serum and urine myoglobin, and creatine kinase levels (CK previously referred to as CPK). Rhabdomyolysis can be caused by a number of conditions including excessive exercise, drugs, congenital muscular dystrophies and inborn errors of metabolism. The most common inborn errors of metabolism include fatty acid oxidation disorders, glycogen storage diseases, and mitochondrial disorders.

This test is indicated for:

  • Individuals with recurrent episodes of rhabdomyolysis.
  • Individuals with an unexplained rise in CPK.


Next Generation Sequencing: In-solution hybridization of all coding exons is performed on the patient's genomic DNA. Although some deep intronic regions may also be analyzed, this assay is not meant to interrogate most promoter regions, deep intronic regions, or other regulatory elements, and does not detect single or multi-exon deletions or duplications. Direct sequencing of the captured regions is performed using next generation sequencing. The patient's gene sequences are then compared to a standard reference sequence. Potentially causative variants and areas of low coverage are Sanger-sequenced. Sequence variations are classified as pathogenic, likely pathogenic, benign, likely benign, or variants of unknown significance. Variants of unknown significance may require further studies of the patient and/or family members.


Next Generation Sequencing: Clinical Sensitivity: Unknown. Mutations in the promoter region, some mutations in the introns and other regulatory element mutations cannot be detected by this analysis. Large deletions/duplications will not be detected by this analysis. Results of molecular analysis should be interpreted in the context of the patient's clinical/biochemical phenotype.

Analytical Sensitivity: ~99%.
