Carrier of DMD and BMD
are at higher than average risk of developing cardiomyopathy. The academy suggests that carriers should undergo a complete cardiac evaluation in late adolescence or early adulthood, or sooner if symptoms occur, and that they should be evaluated every five years starting at age 25 to 30.
There’s some evidence that treatment with angiotensin converting enzyme (ACE) inhibitors and beta blockers can slow the course of cardiac muscle deterioration in DMD and BMD.
This is effective if the medications are started as soon as abnormalities on an echocardiogram (ultrasound imaging of the heart) appear but before symptoms occur.
Some people with BMD who have severe heart problems but generally good health have been successfully treated with heart transplants
Manifesting Carrier of Duchenne Muscular Dystrophin
A mutation in the gene for the muscle protein dystrophin. The classic definition of a disease carrier is someone who can pass the disease to others but doesn't show symptoms. But manifesting carriers are carriers who show {manifest} symptoms of the disease themselves. Some estimates are that as-many as one in ten carriers of DMD or its less severe variant,BMD have signs of the disease themselves. Usually, the signs are relatively mild-but not always
Girls and MD
Do girls ever get DMD or BMD?
Yes, but rarely. A girl almost always has a working dystrophin gene on at least one of her two X chromosomes, and that's usually enough to protect her from skeletal muscle weakness. Heart muscle weakness is another question, however. Female carriers of DMD or BMD can have heart problems even if they don't have skeletal muscle weakness, and some doctors recommend that female relatives of boys with DMD or BMD be checked for these at regular intervals.Occasionally,for complicated genetic reasons, the working dystrophin gene isn't enough to compensate for the flawed one in a carrier, and she develops some generalized muscle weakness. In very rare instances, a girl can be born with no working dystrophin gene on either X chromosome, in which case she develops full-blown muscular dystrophy. Usually, however, when a girl has muscular dystrophy, it's not the Duchenne or Becker type.
