2. Recognize that genetic disorders can affect both physical and mental health. Many genetic disorders have neurological or psychological components, impacting mental health as well as physical traits.
3. Consider the inheritance patterns of genetic disorders. While many genetic disorders are inherited, some can occur spontaneously due to new mutations that are not inherited from the parents.
