Who is Lou Gehrig's

He was a professional baseball player who played for the yankees for 17 seasons. he was known as the iron horse because he played 2130 straight games. Then he got this disease. And had to retire. Marking the end of his career and his life.


I choose ALS because its one of the only disorders I knew about. also because of how much I saw it on the internet last summer. And because it seemed interesting.

How is this disorder inherited-

  • ALS is not sex linked
