This condition affects only males. Muscular Dystrophy It is a muscle disorder that causes weakness of the skeletal muscles, degeneration of the muscles and defective muscle proteins.
Polygenic Disorders Theses genetic disorders are caused by multiple genes and may not be completely inherited but represent a risk factor for certain disease such as diabetes, heart disease, obesity, cancer, and autoimmune disorders.Here we will look at some of the most common genetic NF as one of the most common genetic disorders in inherited blood disorders where.
