- Rheumatoid arthritis
- Crohn’s disease
True or False: Autoimmune diseases can present similar symptoms across different types.
True
What factors can influence the presentation of autoimmune disease symptoms?
- Age
- Hormones
- Environmental factors
List four common symptoms of autoimmune diseases.
- Fatigue
- Low grade fever

- Rash on different areas of the skin
What are the two classifications of autoimmune diseases based on their effect on tissues?
- Organ-specific diseases
- Systemic diseases
How do autoimmune diseases correlate with cancer?
Having an autoimmune disease increases the risk of developing certain cancers due to chronic inflammation.
Name two autoimmune diseases commonly linked to cancer.
- Inflammatory bowel disease
- Multiple sclerosis
What role do genetics play in autoimmune diseases?
Certain genetic risk variants may be responsible, although exact genes have not been fully identified.
What is Type 1 diabetes?
A condition in which pancreatic β-cells are targeted and destroyed by the immune system.
Where is the INS gene located?
On the short arm of chromosome 11p15.5.
What is a significant genetic determinant of Type 1 diabetes?
The major histocompatibility complex (MHC) located on chromosome 6p21.
Which genes are associated with rheumatoid arthritis?

What is the role of T cells and B cells in the immune system?
They are capable of being reactive with self-proteins but are usually regulated to prevent autoimmunity.
What does the Antinuclear antibody (ANA) test identify?
Abnormal proteins produced when the body attacks its own tissues.
What does a complete blood count measure?
Maturity levels, count, and size of blood cells.
