Distribution (number [%]) and allele frequencies of Bulldogs (n = 192) and BRTs (101) with normal (both alleles contain guanine [G] at nucleotide No. 542), carrier (1 allele contains G, and the other contains (thymine [T]), and affected (both alleles contain T) genotypes of the SLC2A9 Cys181Phe mutation, associated with hyperuricosuria in these breeds.
