Understanding SMA (Spinal Muscular Atrophy) - Its Inherited Nature

This post is part of the General "Understanding SMA (Spinal Muscular Atrophy)" series of posts. Therefore, to understand the full concept, we will break it down into parts. This part will discuss its inherited nature. 

• SMA is a recessive disease, which means copies of abnormal genes, that may bring about the disease;
• Family members sometimes have no idea that some contain the recessive disorder;
• If both parents are carriers of the chromosome the risk does increase significantly;
• Genetic testing for the chromosome is available.
