2. Tetany
3. Muscular dystrophy
4. Myasthenia gravis

Answer: Muscular dystrophy

Muscular dystrophy is a group of inherited diseases that damage and weaken your muscles over time.

The muscular dystrophy group contains thirty different genetic disorders that are usually classified into nine main categories or types. The most common type is Duchenne muscular dystrophy (DMD), which typically affects males beginning around the age of four. Other types include Becker muscular dystrophy, facioscapulohumeral muscular dystrophy, and myotonic dystrophy. They are due to mutations in genes that are involved in making muscle proteins. This can occur due to either inheriting the defect from one's parents or the mutation occurring during early development. Disorders may be X-linked recessive, autosomal recessive, or autosomal dominant. Diagnosis often involves blood tests and genetic testing.
