the restriction enzyme ava ii detects the base change of the intervening sequence ii (ivs ii) which is used as one of the markers of β-globin gene polymorphism. this study was conducted to determine the frequency of the ava ii site on the β-globin gene among normal people and patients with sickle cell syndrome (scs) in iran. dna fragments containing the ivs ii region of the β-globin gene from 3...

Background: β-thalassemia is one of the most widespread disease in the world, including Iran. In this study, we reported, for the first time, A 290-bp β-globin gene deletion in the south of Iran. Methods: Four individuals from three unrelated families with Arabic ethnic background were studied in Khuzestan Province. Red blood cell indices and hemoglobin analysis were carried out accor...

Background: Beta thalassemia is a common health problem in Iran especially in Northern provinces. Premarital screening for thalassemia is compulsory in Iran and identification of the carriers is based on primary CBC (Cell Blood Count) and hemoglobin electrophoresis. Silent mutations on β-globin gene have borderline or normal hematological indices that cannot be detected in premarital scree...

Background Luteinizing hormone (LH) is a heterodimeric glycoprotein composed of alpha and beta subunits.This hormone is secreted from the pituitary gland. LH, in women triggers Menstrual cycle and ovulation. In men, LH stimulates production of testosterone, which plays a specialized role in sperm production. Up to day, LH hormone have produced in different ways such as codon optimization and al...

beta thalassemia is the  most common autosomal recessive disorder. the present study reports a rare β globin gene mutation, hbb: c.180g>a: codon 59 (aag/aaa), in a patient from gilan province, northern iran. nucleotide sequencing of amplified dna belonging to a 35 years old man presenting mild hypochromia revealed a synonymous mutation due to a g>a conversion at the third position of codon 59 o...
