Mitochondrial DNA Mutations, Pathogenicity and Inheritance
Mitochondria contain their own DNA (mtDNA), which codes for 13 proteins (all subunits of the respiratory chain complexes), 22 tRNAs and 2 rRNAs. Several mtDNA point mutations as well as deletions have been shown to be causative in well-defined mitochondrial disorders. A mixture of mutated and wild type mtDNA (heteroplasmy) is found in most of these disorders. Inheritance of mtDNA is maternal, a...
متن کاملP-201: Prevalence of 4977bp Deletion in Mitochondrial DNA in IVF Failure Women
Background: Successful IVF process is limited by factors such as oocyte quality. Oocyte quality can be defined as its abilities to be fertilized, mature and give rise to normal offspring and it is dependent on nuclear maturation and cytoplasm maturation. Damage to mitochondrial DNA (mtDNA) has been described in oocytes in IVF failure women that decrease cytoplasmic quality because Mitochondria ...
متن کاملRole of Mitochondria in Ataxia-Telangiectasia: Investigation of Mitochondrial Deletions and Haplogroups
Ataxia-Telangiectasia (AT) is a rare human neurodegenerative autosomal recessive multisystem disease that is characterized by a wide range of features including, progressive cerebellar ataxia with onset during infancy, occulocutaneous telangiectasia, susceptibility to neoplasia, occulomotor disturbances, chromosomal instability and growth and developmental abnormalities. Mitochondrial DNA (mtDN...
متن کاملInvestigation of Polymorphisms in Non-Coding Region of Human Mitochondrial DNA in 31 Iranian Hypertrophic Cardiomyopathy (HCM) Patients
The D-loop region is a hot spot for mitochondrial DNA (mtDNA) alterations, containing two hypervariable segments, HVS-I and HVS-II. In order to identify polymorphic sites and potential genetic background accounting for Hypertrophic CardioMyopathy (HCM) disease, the complete non-coding region of mtDNA from 31 unrelated HCM patients and 45 normal controls were sequenced. The sequences were aligne...
متن کاملThe Mitochondrial DNA 4977-bp Deletion in Patients with Colorectal Cancer: a Case-control Study in Iran
Colorectal cancer (CRC) is the third leading cause of cancer-related death worldwide, and its occurrence can be ascribed to genetic susceptibility. Mitochondrial DNA 4977-bp (mtDNA 4977), as the most described mtDNA deletion, has been long proposed to be involved in various types of cancers. However, a few studies on mtDNA 4977-bp deletion in Iranian patients with CRC have been reported. The cu...
متن کاملMolecular Diversity of Mitochondrial DNA in Iranian Azeri Ethnicities vis-Ã -vis Other Azeris in Asia
In order to investigate the molecular diversity of mtDNA in Azeri population, 133 Azeri subjects inhabitingdifferent regions of Azerbaijan (Iran) were selected. Blood samples were taken from these subjects formtDNA extraction. The extracted mtDNA samples were then studied by the PCR-RFLP method.Fourteen haplogroups were characterized from which 82% were identified as European ...
