Monogenic disorders list  

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