Allele frequency of hereditary equine regional dermal asthenia in American Quarter horses in Brazil determined by quantitative real-time PCR with high resolution melting analysis
MetadataShow full item record
Hereditary equine regional dermal asthenia (HERDA) is a genetic disorder that occurs in the American Quarter horse (AQH) and is caused by a c.115G>A missense mutation in the peptidylprolyl isomerase B (PPIB) gene. Using a quantitative real-time PCR high resolution melting analysis genotyping assay for the PPIB mutation, the estimated HERDA allele and carrier frequencies in a sample of Brazilian AQHs were 2.9% and 5.8%, respectively.
