- Abstract
Resistance to bovine spongiform encephalopathy (BSE) that is significantly associated with insertion/deletion (<italic>indel</italic>) polymorphisms at two loci (putative promoter and intron 1) on the prion protein gene (<italic>PRNP</italic>) in cattle has been well documented. Studies suggest that the insertion alleles are related to BSE resistance. Until recently, BSE has never been reported in water buffaloes (unlike cattle). Previous studies have demonstrated that the <italic>PRNP</italic> gene in water buffalo consists mostly of insertion alleles at both loci; nevertheless, whether or not water buffaloes are genetically resistant to BSE and the role of <italic>indel</italic> polymorphisms in their resistance status is not clear. We examined the coding region of <italic>PRNP</italic> to determine the nucleotide and octapeptide-repeat (octarepeats) variations of Anatolian, Murrah and Murrah × Anatolian (M × A) water buffaloes. Three synonymous single nucleotide polymorphisms (SNP) at positions 126, 234, and 285, and a non-synonymous SNP at position 322 (G108S) were detected. Triplet G/A/T base substitutions were observed at position 126 and two additional genotypes, T/A and T/G, at this position were determined. We also found six octarepeats that indicated the presence of the wild-type <italic>PRNP6</italic> allele in the coding region. To the best of our knowledge, this is the first report of the T/A and T/G genotypes in water buffaloes.
