Genomic organization and analysis of the 5′ end of the porcine ryanodine receptor gene (<i>ryr1</i>)

Abstract

In this study we describe the isolation of genomic clones of the 5' region of the porcine ryanodine receptor gene, a candidate for malignant hyperthermia in pigs and humans. The recombinants were isolated from a porcine liver, genomic DNA library in phage EMBL3A after screening with PCR amplified DNA fragments. The exon/intron structure of the ryanodine receptor gene was determined by DNA sequencing. Based on the sequence data it was possible to develop a simple test for the detection of malignant hyperthermia susceptible and normal pigs.
