Myosin-heavy chain myopathy is a genetic muscle disease that can result in two distinct clinic disease presentations that both involve muscle loss or damage and are linked to the same genetic variant. Screening for MYHM is now included in the American Quarter Horse Association’s genetic health panel. MYHM was added to the panel following a member-submitted rule-change proposal made to the AQHA Stud Book and Registration Committee. At the AQHA Convention, the Stud Book and Registration Committee approved the addition of MYHM to the genetic health panel, with the rule change forwarded to and approved by the AQHA Board of Directors.

AQHA Genetic Health: New Online Resource
Along with testing for MYHM, the Association and AQHA Genetic Health Task Force have launched a new genetic health online resource available at www.aqha.com/genetics.
The new interactive tool educates owners and breeders about how genetic diseases affect an American Quarter Horse, providing information about special care the horse might require and prompting thoughtful breeding decisions. Genetic health panel results should be carefully considered when making thoughtful breeding decisions to prevent further issues to protect future generations of American Quarter Horses.
AQHA is fortunate to have a passionate group of members and scientists who care about the betterment of the American Quarter Horse who volunteer their time to serve on these committees and task forces and provide vital information for the decision-making process.
