Q: What is the dis­ease hy­per­e­las­to­sis cutis?

Horse & Rider - - Your Horse, Your Life -

A:Hy­per­e­las­to­sis cutis (HC), also known as hered­i­tary equine re­gional der­mal as­the­nia (HERDA), is a ge­netic con­nec­tive-tis­sue dis­or­der of the skin. An af­fected horse’s skin may feel mushy or stretchy and doesn’t seem to be “at­tached” over mul­ti­ple ar­eas of the body. The skin is ex­tremely frag­ile, tears easily, and doesn’t heal well fol­low­ing in­jury. There’s no known cure; spe­cial wound treat­ment can help af­fected horses re­main com­fort­able. Horses may carry the gene for HC with­out ex­hibit­ing signs; ge­netic test­ing ( horsetest­ing.com) can re­veal if a horse car­ries the gene, which has been traced to Poco Bueno/King blood­lines in the Quar­ter Horse breed.
