Phenotypic diversity associated with the MT-TV gene m.1644G>A mutation, a matter of quantity.

We describe four patients from three independent families with the m.1644G>A in the MT-TV gene, previously reported without demonstration of its deleterious impact. Very high mutation proportion co-segregated with cytochrome oxidase defect in single muscle fibers and respiratory defect in cybrids as shown by spectrophotometric assays and polarography. The mutation appeared to have a very steep ...

A Novel Nonsense mutation in PANK2 Gene in Two Patients with Pantothenate Kinase-Associated Neurodegeneration

Pantothenate kinase- associated neurodegeneration (PKAN) syndrome is a rare autosomal recessive disorder characterized by progressive extrapyramidal dysfunction and iron accumulation in the brain and axonal spheroids in the central nervous system. It has been shown that the disorder is caused by mutations in PANK2 gene which codes for a mitochondrial enzyme participating in coenzyme A biosynthe...

Analysis of KRAS gene mutation associated with Helicobacter pylori infection in patients with gastric cancer

Objective(s): KRAS proto-oncogene mutation can be considered a diagnostic factor for treating various malignancies. Helicobacter pylori infection, a risk factor for stomach cancer, may cause DNA damage and genetic changes. The aim of the current study was to assess the association of gastric cancer and KRAS mutation, demographic factors, and H. pylori infection.<...

the study of aaag repeat polymorphism in promoter of errg gene and its association with the risk of breast cancer in isfahan region

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...

Molecular dysfunction associated with the human mitochondrial 3302A>G mutation in the MTTL1 (mt-tRNA) gene

The gene encoding mt-tRNA, MT-TL1, is a hotspot for pathogenic mtDNA mutations. Amongst the first to be described was the 3302A.G transition which resulted in a substantial accumulation in patient muscle of RNA19, an unprocessed RNA intermediate including mt-16S rRNA, mt-tRNA and MTND1. We have now been able to further assess the molecular aetiology associated with 3302A.G in transmitochondrial...
