‘Campus’ syndrome pedigree (modified from Tammen et al.). DNA samples were available for this study only from 15 numbered pigs. Note that the founder boar “Campus” was not affected. Four animals used for re-sequencing and mutation screening are indicated by asterisk. The genotypes for the RYR1 mutation causing malignant hyperthermia  (P = mutation, N = wildtype) and the MYH7 c. 4320_4321insCCCGCC genotypes (ins = insertion, wt = wildtype) are given below the symbols.
