Interpretive Summary: Cattle temperament is an economically relevant trait in cattle. Brahman is known to be temperamental when compared to European breeds. Nonsynonymous single nucleotide polymorphisms (nsSNP) are variants in the coding region of the genes where the amino acid is altered in the protein. The objective was to identify nsSNP in candidate genes known to be associated with cattle temperament. Three nsSNP were identified in two genes and evaluated their association with temperament in an independent cattle population. Only one nsSNP in the HTR1B gene was associated with cattle temperament. This gene has been associated with mental disorders in humans, behavior in humans and dogs. It is a suitable single nucleotide polymorphism in a candidate gene to explain differences in behavior in cattle.

Technical Abstract: Three nonsynonymous SNPs (nsSNPs) identified in HTR1B and SLC18A2 candidate genes for temperament were analyzed in silico to determine their effects on protein structure. Those nsSNPs allowing changes were selected for a temperament association analysis in a Brahman population. Transversion effects on protein structure were evaluated in silico for each amino acid change model, revealing structural changes in the proteins of the HTR1B and SLC18A2 genes. The selected nsSNPs were genotyped in a Brahman population (n=138), and their genotypic effects on three temperament traits were analyzed: EV, PS, and TS. Only the SNP rs209984404-HTR1B (C/A) showed a significant association (P=0.0144) with PS. The heterozygous genotype showed a PS value 1.17 points lower than that of the homozygous CC genotype. The results showed that in silico analysis allows the selection of nsSNPs with the potential to change the protein, favoring the prioritization of SNPs associated with temperament in Brahman cattle.
