Monogenic disorders list  

List of monogenic disorders and their associated genes
Monogenic disorders arise from mutations in a single gene, but variations within that gene or in multiple genes can also lead to similar phenotypes, typically following Mendelian inheritance patterns associated with specific genetic changes.
