Genotyping glycogen storage disease type II and type V in cattle reared in the Czech Republic

Genotyping was carried out for glycogen storage disease type II and type V in seven cattle breeds. The analysis was carried out using the polymerase chain reaction/restriction fragment length polymorphism (PCR/RFLP) method. In the breeds analysed [Charolais, Czech Spotted (Czech Simmental), Belgian Blue, Limousine, Blonde d'Aquitaine, Aberdeen Angus, and Beef Simmental sires reared in the Czech Republic], the recessive allele was not found in the PYGM (phosphorylase glycogen, muscle) responsible for the glycogen storage disease type V. In the same panel, the recessive allele in exon 7, exon 9 and exon 13 of the GAA (glucosidase alpha, acid), causing the glycogen storage disease type II was not found. Therefore, we have not revealed the recessives outside previous reported breeds. The knowledge of the breed-specific occurrence of inherited disorders facilitates focusing and reduces the costs of detecting the heterozygous carriers of recessive inherited disorders.
