Abstract:
Aim. To identify associations of mtDNA polymorphisms with sudden cardiac death.Materials and Methods. DNA was isolated from the cardiac tissue excised during the autopsy from individuals who died from sudden cardiac death (n = 260). The frequencies of the most common European mtDNA haplogroups (H, U, T and J) were determined using restriction fragment length polymorphism analysis. In addition, we performed a comparative analysis using previously published data on mtDNA polymorphisms in the West Siberian population.Results. The distribution of mtDNA haplogroups in the patients who died from sud

Abstract:
Mitochondrial DNA (mtDNA) haplogroups have been associated with the expression of mitochondrial-related diseases and with metabolic alterations, but their role has not yet been investigated in morbid obese Caucasian subjects. Therefore, we investigated the association between mitochondrial haplogroups and morbid obesity in patients from southern Italy. The mtDNA D-loop of morbid obese patients (n=500; BMI > 40 kg/m2) and controls (n=216; BMI < 25 kg/m2) was sequenced to determine the mtDNA haplogroups. The T and J haplogroup frequencies were higher and lower, respectively, in obese subje

Abstract:
Mitochondrial DNA (mtDNA) sequence variation was examined in Finns, Swedes and Tuscans by PCR amplification and restriction analysis. About 99% of the mtDNAs were subsumed within 10 mtDNA haplogroups (H, I, J, K, M, T, U, V, W, and X) suggesting that the identified haplogroups could encompass virtually all European mtDNAs. Because both hypervariable segments of the mtDNA control region were previously sequenced in the Tuscan samples, the mtDNA haplogroups and control region sequences could be compared. Using a combination of haplogroup-specific restriction site changes and control region nucle

Objective:To analyse the mitochondrial DNA (mtDNA) haplogroups of patients with hip osteoarthritis (OA) and those of healthy controls in a Spanish population.Methods:mtDNA haplogroups were assigned to 550 cases of hip OA and 505 clinically asymptomatic controls. Sets of controls with healthy knees and hips (n = 179) and patients with knee and/or hip OA (n = 977) were also analysed in a multivariate analysis after adjusting for sex, age and smoking.Results:Individuals carrying haplogroup J showed a significantly decreased risk of developing hip OA (OR 0.661; 95% CI 0.440 to 0.993; p = 0.045).

Abstract:
Background: Multiple sclerosis (MS) is an immunological inflammatory disease of the central nervous system (CNS) which is chronically observed in young adults. On the basis of earlier studies, potential relatedness between MS and mitochondrial DNA (mtDNA) mutations was postulated. Materials and methods: 246 individuals were screened using the PCR-RFLP method, including 70 MS patients examined for mitochondrial haplogroups BM, J, K and M and 176, 149 and 70 normal controls examined for haplogroups BM and M, J and K, respectively.

Abstract:
Abstract Background Polymorphisms in mitochondrial DNA can be used to group individuals into haplogroups that reflect human global migration. These mitochondrial variants are associated with differences in mitochondrial function and have been associated with multiple diseases, including cancer. In this analysis, we evaluated the association between mtDNA haplogroup and risk of myelodysplastic syndromes (MDS). Methods Cases were identified by rapid case ascertainment through the population-based Minnesota Cancer Surveillance System (MCSS). Participants were recruited to the MDS study if they we

Abstract:
Background: Brugada syndrome is a hereditary disease with genetic and phenotypic variability characterized by a high risk for arrhythmia and sudden cardiac death. It is assumed that modifying genetic factors contribute to the variability of the phenotype. Mitochondrial DNA (mtDNA) polymorphism can be considered among such factors, since mitochondrial dysfunction, including that associated with mtDNA variants, can have an arrhythmogenic effect. Aim: To study possible association between mtDNA polymorphism with the phenotype in the Russian patients with Brugada syndrome. Materials and methods: W

Abstract:
AbstractMitochondrial DNA (mtDNA) is highly polymorphic and encodes 13 proteins which are critical to the production of ATP via oxidative phosphorylation. As mtDNA is maternally inherited and undergoes negligible recombination, acquired mutations have subdivided the human population into several discrete haplogroups. Mitochondrial haplogroup has been found to significantly alter mitochondrial function and impact susceptibility to adverse drug reactions. Despite these findings, there are currently limited models to assess the effect of mtDNA variation upon susceptibility to adverse drug reactio

After its Near Eastern emergence, the farming practices rapidly penetrated into southeastern Europe and the first signs of Neolithic in Central Europe are already 7,000 years old. It is being considered that the cultural innovations influenced demographic growth of the populations that have taken part in the Neolithic spread.
