This project is aimed at addressing deficiencies in our current understanding of recurrent laryngeal neuropathy (RLN) through application of progressive and versatile laboratory techniques. Specifically, it is extremely difficult to determine from laryngoscopic evaluation, whether disease will progress to cause a clinical problem. Despite this, there is significant pressure on veterinarians to ‘make this call’ when evaluating yearlings at sale. There is only loose correlation of endoscopic findings and disease pathology, as determined by microscopic studies. Consequently the importance of histopathological disease without clinical signs is not clear. An alternative method to evaluate these horses is needed to: 1) Increase our understanding of the disease process 2) Accurately identify horses with subclinical disease and evaluate the true risk of progression.

1) Investigate with the use of RTPCR, the range of gene expression for MyHC in Thoroughbred racehorses with and without clinical signs of RLN. 2) Evaluate variation in MyHC gene expression in immature and young adult Thoroughbreds. 3) Evaluate clinically unaffected horses for expression of a range of additional genes shown to be dysregulated in neurogenic atrophy.
