A Recessive Inherited Disorder
If a person has a recessive inherited disorder, it implies that they have changed a part of the gene that causes the muscular dystrophy from both of your parents (both your copies of the genes are changed).
When a child gets a mutated version of the gene from one parent, they will become a carrier of the condition. This implies that the child is not affected, but if they get married to another carrier, there is a high risk that one of their children will have the condition.
In some cases, both parents carry a mutated version of the gene that causes muscular dystrophy, this means:
- 1 in 4 chance that their child will be healthy but carry the mother’s faulty gene
- 1 in 4 chance that their child will get muscular dystrophy
- 1 in 4 chance that their child will be healthy but carry the father altered gene
- 1 in 4 chance that their child will be healthy (will not inherit any altered genes)
Several forms of limb-girdle Muscular dystrophy are inherited in this method.
