The DRYK1A gene is located on chromosome 21 and if you are familiar with Down syndrome you might know that people with Down syndrome have 3 copies of chromosome 21 rather than the 2 they are supposed to have which also means they have 2 copies of the genes that are located on chromosome 21 including DYRK1A. Through researching the genes on chromosome 21, to better understand Down syndrome, they learned that DYRK1A gene is an important gene for the brain. (See The Article) In further research they learned that having too much of the gene or too little of the gene both had an effect on mice. There are a few other more common conditions that have led to a better understanding of the DYRK1A gene. Some research done on seizures & autism has provided some very important details of about this rare condition. (Source: http://www.dyrk1a.org/main-blog/rare-common)
