Term Paper On Autism

The final selection underscores technological leaps that have given researchers unprecedented access to the genome — revealing how common genetic variants may contribute to autism, how the condition intersects with others and the potential of various therapies for treating it.

Spontaneous mutations in certain noncoding regions of the genome are linked to autism, according to this analysis of the whole-genome sequences of 1,902 families. The first suggests that common variants modulate the expression of genes that are also affected by rare mutations.

A study from the same group in April showed how analyses in fewer participants can lead to spurious results. The second reveals that common variants contribute to about 8 percent of the risk for developmental conditions thought to arise from rare mutations.

This study also suggests that stimulating this region with an electrical current may ease the effects in mice.

Study of cerebellum’s role in autism homes in on ‘social’ region A region of the cerebellum called the RCrus I may underpin the social problems seen in autistic people and in a mouse model of the condition.

New approach predicts impact of mild mutations in autism The new method outlined in this paper allows researchers to assess the biological impact of thousands of subtle genetic mutations, each of which alters just one of a protein’s amino acids.

In the second — a stem-cell study — scientists used a modified version of CRISPR to restore expression of the gene mutated in the syndrome.

In the first, researchers used gold nanoparticles to successfully deliver CRISPR into the brains of fragile X mice and alter their behavior.

Gene editing via nanoparticles may treat autism syndromes and CRISPR tweak fixes genetic flaw in fragile X syndrome The genetic engineering tool CRISPR could enable researchers to treat fragile X syndrome in the future, according to this pair of studies.

Preoccupations, Perseverations, and Resistance to Change B. Similarly, a high-functioning, older autistic individual may have perseverative interests in such topics as constellations, train schedules, or dinosaurs, and attempt to engage others in conversations on these subjects, while a lower functioning or younger autistic individual might engage in repetitive motor rituals.

A high-functioning, older autistic individual, for example, may attempt to be social, but violate implicit rules of social behavior and be insensitive to unspoken social signals, while a low-functioning or much younger autistic individual may react to other people as if they were little different from inanimate objects.
