Our beautiful Bacardi Gold passed on October 17, 2011 from hypertrophic cardiomyopathy (HCM). In Maine Coons, it is thought to be inherited as an autosomal dominant trait. A DNA-based test for the myosin-binding protein C gene mutation, which has been proven to be causative for HCM in Maine Coon cats, is now available to breeders. Among the grieving family members is my husband, Chris; my father, Paul; my mother, Socorro; and Bacardi’s step-brother, Sambuca and step-sister, Margherita. We know he is now playing joyfully at Rainbow Bridge. He was 14 years of age.
Autosomal dominant is one of several ways that a trait or disorder can be passed down through families. If a disease is autosomal dominant, it means you only need to get the abnormal gene from one parent in order for you to inherit the disease… The abnormal gene “dominates” the pair of genes. If just one parent has a dominant gene defect, each child has a 50% chance of inheriting the disorder. – MedlinePlus
