Lack of Association of Mitochondrial A3243G tRNALeu Mutation in Iranian Patients with Type 2 Diabetes

Many kinds of mutations in mitochondrial (mt) DNA have been reported to be related to the development of Diabetes Mellitus (DM), this type of diabetes has also been shown to be influenced by other genetic factors and/or environmental factors. Among them, tRNALeu(UUR) and its adjacent mtDNA NADH dehydrogenase subunit 1(ND1) region within the mt genome are linked to high susceptibility to DM. A p...

Mitochondrial A3243G mutation with manifestation of acute dilated cardiomyopathy.

A 35-year-old woman (body mass index, 16 kg/m ; height, 140 cm) presented to the emergency ward with severe dyspnea of acute onset. The medical history was noteworthy for bilateral hypacusis treated with a hearing aid. On admission, the laboratory results revealed an N-terminal prohormone of brain natriuretic peptide level of 10 219 ng/L (normal 200 ng/L). Thoracic CT scan excluded pulmonary em...

Varying loads of the mitochondrial DNA A3243G mutation in different tissues: implications for diagnosis.

Testing for common mutations in mitochondrial DNA (mtDNA), including the A3243G MELAS (mitochondrial encephalomyopathy, lactic acidosis, and strokelike episodes) mutation, is routinely done in DNA isolated from blood. Since the blood level of the A3243G mutation may be low in probands and even lower in asymptomatic or oligosymptomatic maternal relatives, we assessed the proportion of A3243G mut...

The mitochondrial A3243G mutation presenting as severe cardiomyopathy.

A 6 year old Portuguese boy with dilated cardiomyopathy had abundant ragged red fibres in muscle (20% of total) and severe lactic acidosis. Molecular genetic analysis showed the A to G transition in the mitochondrial transfer RNALeu(UUR) gene at nt 3243 ("MELAS mutation"), which accounted for 88% and 68% of the total mtDNA in his muscle and blood, respectively. Molecular studies in blood from 1...
