| Author(s) | Study Description | Drug(s) | Sequencing Method | Outcome | Association | Odds Ratio/95% Confidence Intervals/p-value |
|---|---|---|---|---|---|---|
| Di Lorenzo et al. (2009) | 64 individuals with a history of migraines for at least 1 year and had completed an open trial with riboflavin (400 mg) with no concomitant drug treatment | Riboflavin (vitamin B2) | Mitochondrial haplogroups were determined by direct sequencing of the non-coding HVS-1 and HVS-2 regions of mtDNA. Patients were classified into two mtDNA haplogroups: “H” and “non-H” | Riboflavin efficacy in the treatment of migraines | Haplogroup H is a risk factor for treatment inefficacy Decrease in monthly attack frequency after riboflavin treatment was marginal in haplogroup H subjects | 0.24/0.08–0.71/0.054.15/1.42–12.18/0.0001 |
| Esteban et al. (2019) | 91 patients with nAMD who received three initial monthly injections of intravitreal ranibizumab (0.5 mg/0.05 mL) followed by a flexible pro re nata period for 8 months | Ranibizumab | PCR with custom Taqman SNP genotyping assays for four mtDNA haplogroup markers (H: m.7028C>T; HV: m.14766T>C; JT: m.4216T>C; and U: m.12308A>G) | Response to intravitreal ranibizumab treatment in nAMD | After 4 months, BCVA scores were significantly higher for haplogroups HV, JT and U compared with baseline. CFT was significantly lower across all groups. At 12 months, JT BCVA scores were lower and CFT scores were higher than baseline | NR/NR/NRNR/NR/0.004 |
| Guzmán-Fulgencio et al. (2014) | 304 HIV/HCV coinfected patients who had completed a course of HCV therapy | PegIFN-α/ribavirin therapy | Genotyping was performed using the Sequenom MassARRAY platform iPLEX® Gold assay design system | SVR following pegIFN-α + ribavirin treatment | European mtDNA haplogroups were not related to HCV treatment response in HIV/HCV coinfected patients on pegIFN-α/ribavirin therapy | Multiple/Multiple/>0.05 |
| Mittal et al. (2017) | 113 European-Caucasian individuals selected from the CATIE study. Seventy four participants included after confounding factors removed | Risperidone, quetiapine or olanzapine | Mitochondrial genome was enriched by long-range PCR amplification. Products were subsequently purified and sequenced on the Illumina HiSeq 2500 platform | Antipsychotic-induced weight gain | No mtDNA SNPs were significantly associated with % weight change. No significant association between mtDNA phylogenetic groups (H-HV-V, J-T and K-U) and % weight change | NR/NR/NR |
| Subiabre et al. (2015) | 191 warfarin-treated patients from a Chilean population, 91% of which had Amerindian background | Warfarin | Mitochondrial haplogroup characterization was performed using PCR and PCR restriction fragment length polymorphism techniques. Specific endonuclease digestion and gel visualization was used to determine the presence of 3 polymorphic sites in haplogroups A, C and D of the Amerindian population | Warfarin dosage requirements | There were no significant differences in warfarin dosage requirements among the different Amerindian haplogroups | NR/NR/0.083 |
| Wang et al. (2019) | 46 healthy peri/post-menopausal women with intact uteri and ovaries with at least one cognitive complaint and one vasomotor-related symptom | PhytoSERM (selective estrogen receptor β modulator) | Sequencing was performed by dye-terminator sequencing on a 96-capillary 3730xl DNA analyzer | Efficacy of phytoSERM for the management of menopausal symptoms | Haplogroup H had significantly deceased hot flash frequency when treated with 50 mg/day phytoSERM compared with placebo. Haplogroup H placebo subjects had lower baseline LOT scores compared with non-H haplogroups, 50 mg phytoSERM also prevented further decline in the haplogroup H | NR/NR/0.04NR/NR/0.007NR/NR/0.048 |
