FOXP2 is expressed in many areas of the brain, [19] including the basal ganglia and inferior frontal cortex, where it is essential for brain maturation and speech and language development. [20] In mice, the gene was found to be twice as highly expressed in male pups than female pups, which correlated with an almost double increase in the number ...
For example, when individuals suffer from a mutation that causes them to have low levels of serotonin, there is an observed increase in impulsivity and depression [8] With neurotransmitters playing a central role in the development of aggressive behaviour, it follows that many of the gene mutations that have been implicated with aggressive ...
In MDDS associated with mutations in PEO1/C10orf2 that primarily affect the brain and the liver, symptoms emerge shortly after birth or in early infancy, with hypotonia, symptoms of lactic acidosis, enlarged liver, feeding problems, lack of growth, and delay of psychomotor skills. Neurologically, development is slowed or stopped, and epilepsy ...
Genes involved in the neuro-development and in neuron physiology are extremely conserved between mammalian species (94% of genes expressed in common between humans and chimpanzees, 75% between humans and mice), compared to other organs. Therefore, few genes account for species differences in the human brain development and function. [15]
Certain genes influence the volume of key brain regions, which, in turn, could play a role in the development of Parkinson's disease and ADHD, a new study suggests. Parkinson’s, ADHD tied to ...
Human somatic variations are somatic mutations (mutations that occur in somatic cells) both at early stages of development and in adult cells.These variations can lead either to pathogenic phenotypes or not, even if their function in healthy conditions is not completely clear yet.
Interacting with dogs in such ways may strengthen people’s brain waves associated with rest and relaxation, as measured by brain tests, according to a small study published Wednesday in the ...
Small-scale mutations affect a gene in one or a few nucleotides. (If only a single nucleotide is affected, they are called point mutations.) Small-scale mutations include: Insertions add one or more extra nucleotides into the DNA. They are usually caused by transposable elements, or errors during replication of repeating elements.
