A type of Health Concern that embodies a risk that the patient may be particularly susceptible to a given disease due to the fact that a relative of the patient had experienced the condition. For example, if a female patient's mother had breast cancer, then the patient may have a higher risk of breast cancer. While this class is generally used for conditions to which the patient may be genetically pre-disposed, such as breast cancer, and therefore will generally reference blood relatives, it may also be used to document environmental risks that the patient shares with extended family members.
