Application of oligonucleotide array CGH in the detection of a large intragenic deletion in POLG associated with Alpers Syndrome.

Abstract excerpt

Mutations in the polymerase γ (POLG) gene are among the most common causes of mitochondrial disease and more than 160 POLG mutations have been reported. However, a large proportion of patients suspected of having POLG mutations only have one (heterozygous) definitive pathogenic mutation identified. Using oligonucleotide array CGH, we identified a compound heterozygous large intragenic deletion encompassing exons...
