Targeted aCGH for mitochondrial and metabolic disorders

Posted by & filed under Part 10: DISORDERS OF MITOCHONDRIAL FUNCTION, Tools.

Targeted aCGH can be useful in the diagnosis of mitochondrial and metabolic disorders. Wang et al. have developed a custom designed oligonucleotide aCGH platform targeting the entire mitochondrial genome and a set of nuclear genes involving mitochondrial and metabolic disorders. This technology can be used to evaluate large deletions, particularly as a complementary diagnostic test in the context of a recessive disease when only one mutant allele is found by sequencing. It also has applications in X-linked metabolic disorders when sequencing analysis for a female carrier is negative.
