Noonan syndrome is a developmental disorder. Noonan syndrome is a genetical disorder. Nuerofibromatosis 1 (NF1), Noonan Syndrome (NS), Costello syndrome, cardiofaciocutaneous syndrome(CSC) are autosomal dominant disorders. All these diseases leads to mental disorders. As these are autosomal dominant disorders, one mutated copy of gene is enough to get the disease. One of the parent might be a carrier of the gene, get affected with the disease and pass the gene to the children. Both males and females get affected equally as one gene is enough to get the disease. Due to a sudden mutation in any gene also cause the autosomal dominant disorder.
