What Is Muscular Dystrophy?
9. Fukuyama CMD
Congenital muscular dystrophies (CMD) are those that are apparent soon after birth, sometimes called “floppy baby syndrome.” They are marked by poor muscle tone and weakness. Because newborns may have trouble feeding, weight gain and growth are delayed. There is usually a shortened life span with CMD, even though the disease progresses slowly.
Fukuyama is one of two specific kinds of CMD that have been identified. Although rare in the United States, Fukuyama is the second most frequently seen CMD in Japan. It causes muscles to contract, leading to joint problems. Sometimes babies have elbows and knees in fixed positions. Sucking and swallowing are difficult. Mental retardation is not uncommon, and some infants have seizures.
