Warmblood Fragile Foal Syndrome causative single nucleotide polymorphism frequency in Warmblood horses in Brazil.

Warmblood Fragile Foal Syndrome (WFFS) is an autosomal recessive genetic disorder caused by a mutation in the procollagen-lysine, 2-oxoglutarate 5-dioxygenase 1 (PLOD1) gene, associated with collagen biosynthesis. WFFS causes lesions and malformations of the skin in neonatal foals, and abortion. The objective of this study was to investigate the allelic frequency of the single nucleotide polymorphism (SNP) c.
