HERNANDEZ, Darwin Y; POSSO TERRANOVA, Andrés Mauricio  e  JAIME EDUARDO, Muñoz Flórez. Detection of a single mutation point in Ryanodine receptor gene (Ryr 1) in colombian creole pigs. Acta Agron. [online]. 2008, vol.57, n.4, pp.275-278. ISSN 0120-2812.

The Porcine Stress Syndrome is a hereditary monogenic recessive disease related with Ryanodine Receptor gen (Ryr1). Using PCR-SSCP and PCR-RFLP 14 animals of commercial breed with Mule foot characteristic (CM), 21 San Pedreño breed (SP) and 100 Zungo breed (ZN) were genotipificated. Allelic frequency for CM and SP was the same (F(H) = 0.79 y F(h) = 0.21), while in ZN there was no evidence of recessive allele (h). Heterocigosity (He) was 0.28% for CM and 0.23% for SP. He value for population sample was 0.066.
