Sequencing and identification of single nucleotide polymorphisms of Partial myostatin gene in dromedary and Bactrian camels

Abstract

Myostatin (MSTN) is a member of the transforming growth factor-β superfamily (TGF-β) and is an important negative regulator of muscle growth in vertebrates. In this study, a partial sequence of MSTN gene (intron 1), in the camel population of Iran, was evaluated. Two single nucleotide polymorphisms and one insertion or deletion (InDell) were identified in intron 1 of the myostatin gene, using sequencing method. The mutations caused, two substitutions including C to T and T to C in positions 16 and 136, respectively and one InDell of T in position 218. The mutations observed in three positions of intron 1, created three different haplotypes. These haplotypes were shared among Bacterianus and Dromedaries camel populations with no haplotype restricted to a specific region or a single camel breed. Tajima D were positive for all populations except Trod station, but it wasn’t significant.
