Document Summary
It"s important to know about the genetics because by studying gene-behaviour relationships in neurodevelopmental disorders that have a strong genetic origin we can: Improve diagnostic reliability; reduce time to diagnosis; tease apart the causes of problem behaviours; develop sensitive and appropriate treatment options. Neurodevelopmental disorders: neurodevelopmental disorders are the result of impairments to the typical growth or development of the brain and nervous system. Common childhood neurodevelopmental disorders: single gene disorders: fragile x, williams syndrome, polygenic disorders: autism spectrum disorder (asd), adhd, tourette syndrome, specific language impairment, dyslexia, intellectual disability. Genes, alleles, and snps: genes: distinct sequence of dna forming part of a chromosome, which is the blueprint for a protein (e. g. , neurotransmitter, receptor, parts of a neuron, each chromosome is composed of one large dna molecule. Genetic variation: how certain gene variants increase the risk for developing neurodevelopmental disorders. You can estimate heritability from parents to offspring, compare siblings, compare twins.
