Abstract: 

Objective: Pompe disease is a rare neuromuscular genetic disorder and is classified into two forms of early and late-onset. Over the past two decades, mitochondrial abnormalities have been recognized as an important contributor to an array of neuromuscular diseases. We therefore aimed to compare mitochondrial copy number and mitochondrial displacement-loop sequence variation in infantile and adult Pompe patients.
Materials and Methods: In this retrospective study, the mitochondrial D-loop sequence was analyzed by polymerase chain reaction (PCR) and direct sequencing to detect possible variation in 28 Pompe patients (17 infants and 11 adults). Results were compared with 100 healthy controls and sequences of all individuals were compared with the Cambridge reference sequence. Real-time PCR was used to quantify mitochondrial DNA copy number.
Results: Among 59 variants identified, 37 (62.71%) were present in the infant group, 14 (23.333%) in the adult group and 8 (13.333%) in both groups. Mitochondrial copy number in infant patients was lower than adults (P<0.05). A significant frequency difference was seen between the two groups for 12 single nucleotide polymorphism (SNP).
A novel insertion (317-318 ins CCC) was observed in patients and six SNPs were identified as neutral variants in controls. There was an inverse association between mitochondrial copy number and D-loop variant number (r=0.54).
Conclusion: The 317-318 ins CCC was detected as a new mitochondrial variant in Pompe patients.
