D. B. S. Silva, Crispim, B. A., Silva, L. E., Oliveira, J. A., Siqueira, F., Seno, L. O., and Grisolia, A. B., Genetic variations in the leptin gene associated with growth and carcass traits in Nellore cattle, vol. 13, pp. 3002-3012, 2014.

The aim of the study was to detect polymorphisms in the leptin gene and to determine the association of these polymorphisms with growth and carcass traits in Nellore cattle. The single nucleotide polymorphisms (SNPs) -1457 (AJ571671:g.-1457A>G) and A59V (AF536174.1:g. 321C>T), as well as the microsatellite BM1500 (3.9 kb downstream), were genotyped. The measures of body weight and ultrasound examinations (rib eye area, back, and rump fat thickness) were performed in 3 different periods of animal management.
