Autism Is A Genetic Disorder - 907 Words

Although autism has spread globally, scientists continue conducting research to identify the precise causes. More specifically, they are zeroing in on genetic mutations, brain chemistry abnormalities, and maternal factors. One possible cause that can lead to autism is genetic mutations. First of all, families studies indicate that children can affected by autism through heredity. It is true that children inherited some characteristics from their parents. This is because a chromosome of a child produced by one chromosome father and the other one from mother, which formed as DNA. As a matter of fact, if parents have some genetic disease, they can pass it to the offspring through DNA. In same way, because autism is a genetic disorder, it can pass down generation. In fact, according to Cowley (2000), the prevalence of having autistic child is 5% of family who already has this disorder, which means around 25 times the normal average. Clearly, inheriting autism through families result in i ncreasing the number of autistic children in the population. Another evidence shows that autism can caused by inheriting genetic disorder is through conducting twins studies. There are two types of twins. First one is identical twins, which formed by splitting one fertilized egg and then developed in two babies. Therefore, they are sharing the same genetic codes. However, this different from fraternal twins who do not share the same genetic information because they are formed by twoShow MoreRelatedAutism Spectrum Disorder And Genetics1437 Words   |  6 PagesAutism Spectrum Disorder and Genetics ASD stands for Autism Spectrum Disorder and since the early 1900’s; it has been a mystery to many researchers and psychologists. Autism is usually noticed in the first three years of life but there are many theories on which it comes about. Before the 1940s, children who showed signs of Autism Spectrum Disorder were labeled schizophrenic, emotionally disturbed, and psychotic (Kartemquin, 2008).

Autism is a disorder that affects a childs ability to develop normally and communicate effectively. Autism is found in all racial, ethnic and socioeconomic groups (â€Å"Data Statistics†). With modern treatments, it is possible for a child with autism to live a somewhat normal and healthy life.

Essentially, the term means an â€Å"isolated self† or a person excluded from social interactions. In the 1940s, researchers in the United States modified the term to describe children who experienced emotional or social problems. Thus, relinquishing the word â€Å"autism† from its connection to schizophreniaRead MoreEthical Implications Of Mandatory Genetic Testing For Autism Spectrum Disorders2398 Words   |  10 PagesImplications of Mandatory Genetic Testing for Autism Spectrum Disorders in Children For most of the 20th century, scientists were not equipped with the technology while parents were not fully aware of the social, behavioral, and communicative challenges associated with children having Autism Spectrum Disorder (ASD).

The genetics of neurodevelopmental disorders (NDD) rarely display a Mendelian mode of inheritance, and can result from a single rare gene mutation, more common variations in single nucleotide polymorphisms, or often a combination of these two factors in conjunction with environmental influences [1]. In contrast, epigenetic mechanisms are heritable changes in gene expressionRead MoreCommon Chromosomal Abnormalities Associated With Autism1434 Words   |  6 PagesFive other gene disorder that contributes to autism are (1) EN2 (Engrailed 2) involved in cerebellum development. (2) GABR (Gamma Amino Butyric Acid Receptor) regulates brain cell migration. (3) OXTR (Oxytocin Receptor) participating in the response to stress and social skills. (4) RELN (Reelin) involved in neuronal migration in the developing brain. (5) SLC6A4, a serotonin transporter gene† (Johnson, Giarelli, Lewis, Rice, 2013).

This disorder can range from mild to severe and is shown in many different forms.

Actress Holly Robinson Peete once stated, â€Å"I m not a doctor or scientist. I m just a mom. But I do think there s a genetic predisposition, and there are environmental triggers.
