چکیده

A general method is presented for the direct selection of transductional clones of Salmonella containing suppressor mutations. The supD locus is about 40% cotransducible with the closest fla markers examined. The probable map order is: supD501-(flaD42-flaB36)-(flaA41-flaA37).

Mutation Analysis of GJB2 and GJB6 Genes and the Genetic Linkage Analysis of Five Common DFNB Loci in the Iranian Families with Autosomal Recessive Non-Syndromic Hearing Loss

The incidence of pre-lingual hearing loss (HL) is about 1 in 1000 neonates. More than 60% of cases are inherited. Non-syndromic HL (NSHL) is extremely heterogeneous: more than 130 loci have been identified so far. The most common form of NSHL is the autosomal recessive form (ARNSHL). In this study, a cohort of 36 big ARNSHL pedigrees with 4 or more patients from 7 provinces of Iran was investig...

Genetic evidence for a switching and energy-transducing complex in the flagellar motor of Salmonella typhimurium.

The flaAII.2, flaQ, and flaN genes of Salmonella typhimurium are important for assembly, rotation, and counterclockwise-clockwise switching of the flagellar motor. Paralyzed and nonchemotactic mutants were subjected to selection pressure for partial acquisition of motility and chemotaxis, and the suppressor mutations of the resulting pseudorevertants were mapped and isolated. Many of the interg...

Investigating Seven Recently Identified Genes in 100 Iranian Families with Autosomal Recessive Non-syndromic Hearing Loss

Objectives: Hearing loss (HL) is the most common sensory disorder, and affects 1 in 1000 newborns. About 50% of HL is due to genetics and 70% of them are non-syndromic with a recessive pattern of inheritance. Up to now, more than 50 genes have been detected which are responsible for autosomal recessive non-syndromic hearing loss, (ARNSHL). In  Iran, HL is one of the most common disabilitie...

The Prevalence of P53 Mutations in Laryngeal Cancer in Kerman

Background &Aims: Laryngeal cancer is the second common cancer of respiratory tract, following the lung cancer. Carcinogenesis is a complex multistage process; molecular genetics has provided the evidence that activation of proto-oncogene and loss or inactivation of tumor suppressor genes (TSG) are involved in a large number of malignancies. One of the earliest significant tumor suppressor gene...

The Spectrum of Mutations in 100 Thalassemic Carriers Referred to Ghaem Hospital of Mashhad

Abstract Background Thalassemia is common in the Iranian population, and it must be considered in the differential diagnosis of the microcytic hypochromic anemia. The molecular analysis of β-thalassemia is necessary for prenatal molecular diagnosis. Α-thalassemia caused by loss of function of either one of the two duplicated α-globin genes or in less frequent non deletion mutations mostly loc...
