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...
متن کاملThe 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...
متن کاملLack 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...
متن کاملNovel m.15434C>A (p.230L>I) Mitochondrial Cytb Gene Missense Mutation Associated with Dilated Cardiomyopathy
Background. Previously it has been shown that various types of hypertrophic and dilative cardiomyopathy (hCMP, dCMP) can be attributed to disturbed mitochondrial oxidative energy metabolism. Several studies described mutations in mitochondrial DNA-located genes encoding for subunits of respiratory chain complexes, including the cytochrome b gene (MT-CYB), causing CMPs. Methods and Results. In t...
متن کاملSignificance of sarcomere gene mutation in patients with dilated cardiomyopathy.
Dilated cardiomyopathy (DCM) is a myocardial disease with a high mortality rate. Approximately 40 genes have been found to be associated with DCM to date. Non-familial DCM can also be caused by gene mutations, suggesting that genetic factors were involved in the pathogenesis of DCM; therefore genetic testing is beneficial for the early diagnosis of DCM, which can facilitate the implementation o...
