Background and Objective: Janus kinase 2 (JAK2) and Myeloproliferative Leukemia (MPL) mutations are confirmatory indicators for Myeloproliferative Neoplasm (MPN). The current study was performed to determine the frequency of MPL mutation in MPN patients without JAK2 mutation, in order to assign MPL mutation frequency in North-East of Iran.Methods: Total o...
wiskott-aldrich syndrome (was) is a life-threatening x-linked recessive immunodeficiency disease described as a clinical triad of thrombocytopenia, eczema, and recurrent infections, caused by mutations of the was protein (wasp) gene. the milder form of this disease is x-linked thrombocytopenia (xlt) that presents only as platelet abnormalities. mutation analysis for 15 boys with wiskott-aldr...
congenital recessive myotonia is a rare genetic disorder caused by mutations in clcn1, which codes for the main skeletal muscle chloride channel clc-1. more than 120 mutations have been found in this gene. the main feature of this disorder is muscle membrane hyperexcitability. here, we report a 59-year male patient suffering from congenital myotonia. he had transient generalized myotonia, which...
context cystic fibrosis (cf) is the most widespread autosomal recessive genetic disorder that limits life expectation amongst the caucasian population. as the median survival has increased related to early multidisciplinary intervention, other manifestations of cf have emergedespecially for the broad spectrum of hepatobiliary involvement. the present study reviews the existing literature on liv...
background nucleus(t)ide analogs (nas), containing lamivudine (lmv), adefovir dipivoxil (adv), endeavor (etv), telbivudine (ldt), and tenofovir (tdf) are widely used for the treatment of chronic hepatitis b (chb), but long term anti-hepatitis b virus (hbv) therapy with nas may give rise to the emergence of drug-resistant viral mutants. objectives this study aimed to find and identify some new r...
• Mutation-selection balance at two linked loci can be fully investigated. Dynamics of loss wild-type alleles depend on the type epistasis. After Muller's ratchet clicks, a deleterious allele is fixed by selection. We report complete analysis deterministic model mutations and negative selection against them haploid without recombination. As long as mutation weaker force than selection, mutant r...
background: the frequency of pyruvate kinase (pk) deficiency, an autosomal recessive defect, is approximately 3 per 10,000 individuals in shiraz and surrounding areas, and is increased due to high consanguinity marriage frequency. the purpose of this study is to obtain data on the frequency and spectrum of gene mutation of pk in newborns, from shiraz and surrounding areas. materials and methods...
cystic fibrosis (cf) is the most common severe autosomal recessive disorder caused by a wide spectrum of mutations in the gene encoding for the cystic fibrosis transmembrane conductance regulator (cftr) protein. the frequencies, types and distributions of mutations vary widely between different populations and ethnic groups. the aim of this study was to perform a comprehensive analysis of the c...
background: iran has a large group of patients with severe congenital factor xiii deficiency (fxiiid) and trp187arg mutation that is most disease causing mutation of fxiii in the world is only observed in southeast of iran with 352 patients with fxiiid. 743 patients with fxiiid was observed in 17 provinces of iran but tehran city with more than 12 million population has no any registered patien...
Objective(s):Sulfur mustard (SM) was used by the Iraqi army against the Iranian troops in the Iran-Iraq war from 1983–1988. This chemical gas affects different organs including the skin, lungs and the hematopoietic system. Any exposure to SM increases the risk of chromosomal breaking, hyperdiploidy and hypodiploidy. Studies have shown that the risk for acute myeloblastic and lymphoblastic leuke...
