The effects of trisomy 12 may be due to gene dosage effect, with increased expression of a number of genes, including HIP1R, CDK4, and MYF6, located on chromosome 12. For instance, Down syndrome, the most common genetic disorder in humans, is referred to as trisomy 21 because there is an extra copy of chromosome 21 in the nucleus of each cell.
