Mutations can cause genetic disorders when they result in non-functional proteins being produced. There are three main types of mutations: deletions which remove DNA, insertions which add DNA, and substitutions which switch DNA bases. Autosomal dominant disorders are caused by a dominant mutated gene inherited from a parent, giving children a 50% chance of being affected.

Mutations and Autosomal Dominant Disorders Genetic Mistakes
Mutations Mutation a change in the DNA message Mutations cause the wrong protein to be made (they may no longer be functional)
3 Types of Mutations Deletion section of DNA removed Insertion section added Substitution bases switched
Causes of Mutations Errors in replication or transcription Powerful radiation: x-rays, UV light, etc.
Genetic Diseases Can be caused by mutations or by additional/fewer chromosomes CCMs are an autosomal dominant genetic disorder.
Autosomal Dominant Disorders The mutated gene is dominant and presents in one parent. The children have a 50% chance of being affected.
