Circulating concentrations of a marker of type I collagen metabolism are associated with hypertrophic cardiomyopathy mutation status in ragdoll cats.

Circulating CITP was higher in MYBPC3-positive ragdoll cats than negative controls and may indicate altered collagen metabolism. Further studies are necessary to determine whether alterations in circulating collagen biomarker concentration relate to an early stage of hypertrophic cardiomyopathy.
