Forty six Saudi samples were collected from obese and non-obese males aged between 25 and 35 years old. Approximately 1000 bp of the mitochondrial cytochrome b gene for these samples were amplified and sequenced as an initial effort to determine the sequence variation within this mtDNA coding region. The sequenced fragment was aligned with its counterparts from 100 healthy African and Asian humans found in the Genbank database. The polymorphisms of these sequences were analyzed for forensic purposes. A total of 12 polymorphic sites and 25 variations were noted. Sixteen out of the 25 variations were synonymous and the other 9 encoded different amino acids (non-synonymous). The haplogroup of all samples was determined using Mitomaster software. A total of 5 common different haplogroups were observed (H2a, U5a, JT, L3 and R0a). The recorded SNPs were tribe other than obesity-dependent except one common SNP (C15452A) which seemed to be an obesity marker, however, it was also found in the non obese individuals. Although the polymorphisms of cytochrome b gene were observed in Saudi populations and could be considered as a powerful forensic marker, however, more samples must be analyzed to investigate the unique distribution for forensic applications.
