Identification of complex vertebral malformation carriers in Chinese Holstein.
Complex vertebral malformation (CVM) is a monogenic autosomal recessive hereditary defect of Holstein dairy cattle. It is caused by a point mutation from G to T at the nucleotide position 559 in bovine solute carrier family 35, member 3 gene (SLC35A3), which changes the amino acid sequence of uridine 5'-diphosphate-N-acetylglucosamine transporter protein from a valine to a phenylalanine in position 180. The elite U.S. Holstein sire Penstate Ivanhoe Star was identified as the common ancestor of the current CVM carriers. Because his offspring, mainly those of Carlin-M Ivanhoe Bell, were used in many countries, CVM has potentially spread into China. In the present study, using the polymerase chain reaction-single-stranded conformational polymorphism (PCR-SSCP) technique, 10 CVM carriers were found among 68 at-risk Chinese Holstein bulls, and 282 carriers were found among 602 at-risk cows. The results of this study indicate that the CVM gene exists in the Chinese Holstein population.
