Schematic representation of the DNA polymorphisms detected in canine CMAH. Genomic structure of the CMAH gene from dog was obtained by comparative analysis of mRNA sequences and whole genome shotgun sequence (Accession No. NC_006617.3, chromosome 35). □: Exon (UTR), ■: CDS, ▬: Intron. The position of the identified DNA polymorphism was numbered from the A of the initiator methionine ATG codon considered to be + 1, as revealed in the exon. In introns, a positive number indicates the number of nucleotides from the previous exon, whereas a negative number indicates the number of nucleotides from the next exon
