Maternal inheritance of mitochondria creates a sex-specific selective sieve with implications for male longevity, disease susceptibility and infertility. Because males are an evolutionary dead end for mitochondria, mitochondrial mutations that are harmful or beneficial to males but not females cannot respond directly to selection. Although the importance of this male/female asymmetry in evoluti...

objective: colorectal cancer (crc) is one of the most common and aggressive cancers worldwide. the majority of crc cases are sporadic that caused by somatic mutations. the adenomatous polyposis coli (apc; omim 611731) is a tumor suppressor gene of wnt pathway and is frequently mutated in crc cases. this study was designed to investigate the spectrum of apc gene mutations in iranian patients wit...

background: this study investigated the association between pfcrt, t76 allele and chloroquine resistance in patients with falciparum malaria. molecular assays for point mutations on drugs resistance-related genes are applied tools for monitoring emerging resistance and surveillance malaria control strategies in endemic areas. the mutant genotype at codon 76 of plasmodium falciparum chloroquine ...

Wolfram syndrome (WS) is a rare autosomal recessive neurodegenerative disease with variable symptoms, including neuropsychiatric manifestations. A 26-year-old man was reported with classic symptoms of WS and repetitive psychiatric hospitalizations and at least 16 suicidal attempts. The genetic study demonstrated a novel homozygous stop-codon mutation on the WFS1 gene. This special type of mutat...

autosomal polycystic kidney disease (adpkd) is a genetic disorder with two causal pkd-1 and pkd-2. genetic studies have demonstrated an important allelic variability between patients but few data are known about genetic variants in african populations. we report a new mutation found in a 41-year old women with mild chronic kidney disease secondary to adpkd. molecular genetic testing found a del...

Large numbers of genes are responsible for Leigh syndrome (LS), making genetic confirmation of LS difficult. We screened our patients with LS using a limited set of 21 primers encompassing the frequently reported gene for the respiratory chain complexes I (ND1-ND6, and ND4L), IV(SURF1), and V(ATP6) and the pyruvate dehydrogenase E1α-subunit. Of 18 LS patients, we identified mutations in 11 pati...

Background: Co-inheritance of hemochromatosis (HFE) gene mutations may play an essential role in the pathogenesis of iron overload in beta-thalassemia major (BTM) patients. The present study aimed to investigate the prevalence of HFE C282Y and H63D mutations in BTM patients and their correlation with some demographic data and biochemical iron markers. Materials and Methods: The study populat...

aim : we aimed to explore the frequency of braf v600e mutation in iranian patients with colorectal cancer (crc) as well as its association with clinic pathological characteristic of patients.   background : crc is the third leading cause of cancer related death. there is a growing body of data showing the association of braf v600e mutation with malignant transformation and clinical outcome of d...
