ABSTRACT
We investigated the genotype distribution of hepatitis C virus [HCV] among Saudi patients with chronic hepatitis C. Serum specimens from 119 native Saudi Arabian patients with chronic hepatitis C, as documented by serology and polymerase chain reaction [PCR] for HCV RNA, were used. Genotyping was performed by reverse transcription-PCR, using specific primers at the core region of HCV genome, and DNA sequencing of the resultant amplicons. It was found that the majority of samples [47.9%] belong to genotype 4, followed by subtype Ib [16.8%], and subtype la [10.1%]. Twenty samples [16.8%] were not able to be typed by our method. We confirmed the results by cloning at least one PCR amplicon from each genotype, and determining the nucleotide sequence of the clones. Our findings suggest that genotype 4 is the most common among native Saudi Arabian patients with chronic hepatitis C infection. Genotypes Ib and la were also prevalent
