Fluctuation of Gene Frequency in Sub-populations Originatedfrom One Guppy Population.

Allele Frequency of CYP2C19 Gene Polymorphisms in a Healthy Iranian Population

Cytochrome P450 2C19 (CYP2C19) plays an important role in the metabolism and elimination of a wide range of medications. The polymorphisms of this enzyme give rise to substantial inter-individual and inter-ethnic variability in drug excretion rates and final serum concentrations. For this reason, therapeutic re-sponses and adverse drug reactions may vary from one person to another. In this stud...

Relative Frequency of 35delG Mutation in GJB2 Gene in Autosomal Recessive Non-Syndromic Hearing Loss (ARNSHL) Patients in Kerman Population

Congenital hearing loss with many genetic and environmental causes affects 1 in 1000 newborns. Mutations in the GJB2(Gap Junction Beta-2) gene encoding the gap junction protein connexin 26 have been established as the main cause of autosomal recessive non-syndromic hearing loss. The aim of this study was to study the frequency of one mutation (35delG) of GJB2 gene in Kerman non-syndromic deaf p...

Relative frequency of GJB2 gene mutations in autosomal recessive non-syndromic hearing loss (ARNSHL) patients in Lorestan population

Background: Congenital hearing loss due to different genetic and environmental causes affects 1 in 1000 newborns. Mutations in the GJB2 (Gap Junction Beta-2) gene encoding the gap junction protein connexin 26 have been established as the main cause of autosomal recessive non-syndromic hearing loss. Materials and methods: The aim of this study was to study the frequency of GJB2 Mutations in Lor...
