Hey Awesomites
Many cells in the brain express two copies of a gene - maternal and paternal. But some express only one. If the single copy that is expressed carries a genetic mutation, it may result in cellular dysfunction and thus there are consequences.
Research on newborn mouse suggests that in about 85 percent of genes in the dorsal raphe nucleus, known for secreting serotonin, differentially activate their maternal and paternal gene copies. Ten days later in the juvenile brain, both copies are activated equally for all but 10 percent of genes.
The disparity also occurs in humans and in other systems like liver and muscles.
Like for example, in humans, a gene called DEAF1 that is implicated in autism and intellectual disability, shows a preferential expression of one copy of genes in multiple areas of brain. This is true for genes in other mental and neurologic disorders like Huntington's disease, schizophrenia, ADHD, and bipolar disorder.
