Several genetic risk factors have been identified across various diseases. For example:
BRCA1 and BRCA2 genes: Mutations in these genes significantly increase the risk of breast and ovarian cancers. APOE ε4 allele: This allele is associated with a higher risk of developing Alzheimer's disease. HLA genes: Certain variants of HLA genes are linked to autoimmune diseases such as type 1 diabetes and rheumatoid arthritis. Factor V Leiden: A mutation in this gene increases the risk of developing blood clots and deep vein thrombosis.
