WebThe Prader-Willi syndrome (PWS) and Angelman syndrome (AS) are two distinct neurogenetic diseases that are caused by the loss of function of imprinted genes on the proximal long arm of human chromosome 15. In a few percent of patients with PWS and AS, the disease is due to aberrant imprinting and gene silencing. WebThe genes that specify how to make each of the four proteins are split across two chromosomes. This means that each chromosome consists of two genes. Since the proteins specified by the genes all have four amino acid monomers, each gene must have four codons.
