Autism is significantly caused in people by de novo mutation, deletions, duplications, genomic rearrangements, or point mutations in the germ line of one parent that causes loss of function or gain of function to a large number of genes. This can occur in any family with any genetic background and can appear in any offspring, regardless of gender. Offspring’s with mild disorders (asymptomatic carriers) i.e., females may marry and have children who inherit mutations in a dominant way. It is now obvious that the third-born male child is at high risk, i.e., his probability of being affected in comparison to the first two children being affected is nearly 50% with dominant transmission and high penetration. Females are at lower risk (20%) with lower incidence in females and reduced penetration in that gender. Explanation is yet to be given about disruptions on a single chromosome with incomplete penetrance that creates carrier states. [30] Females are resistant and therefore make logical carriers, but discordance between monozygotic twins suggest Autism Spectrum Disorder genotype and exi...
Genetic disorders can be caused by many of the 46 chromosomes in human cells. This specific disorder is linked to a mutation in the long arm of the X, or 23rd chromosome. The mutation is recessive, meaning a normal X chromosome can hide it. Females have two X chromosomes allowing them to hide the mutated recessive one, making them a carrier of the gene, while males only have one X chromosome, meaning that they are unable to hide the mutation and they become effected by the disease. Therefore if a male carries the gene, he is affected because he has no way of dominating the recessive gene, but if a female carries it, she is only a carrier and has a 50/50 chance of passing it on to her baby. This may seem like a high probability however, only one in every fifty thousand male births will have this immunodeficiency disease.
According to Autism Speaks Inc. (2015) research has determined there are more than 100 autism risk genes. Both Autism Speaks Inc. (2015) and Autism Society agree that there is a high genetic factor in children with autism, as well as an environmental risk factor. Autism Speaks Inc. (2015) suggests that many things can be responsible for autism in children. Some of these things include parental age, maternal illnesses, extreme prematurity, low birth weight and oxygen deprived babies. According to CDC (2015) people who are older who are having kids are putting their child at a higher risk of being diagnosed with
...sorders on the spectrum such as AS. Several of the sources used in the composition of this paper refer to the belief that Autism is a form of “extreme male brain”, an exaggeration of male traits caused by high levels of testosterone while in utero. In spite of the disparity between the two genders, there are girls struggling with this disorder, and they often experience more severe symptoms than their male counterpart (Rudacille).
One of the most characteristic features of Autism Spectrum Disorders (ASD) is its prominent higher prevalence among the male gender in comparison with the female gender. Although rates of ASD are consistent across cultures, these rates vary significantly by gender. It is the male gender that seems to be more affected by ASD with an average male-to-female ratio of 4.2:1, affecting 1 in 70 males and only 1 in 315 females (Fombonne, 2009). Although a well-known fact, the causes for such a great difference among sex ratios still remains unexplained, there are several hypotheses and studies trying to explain the reason for this inequality. In this paper I will outline some of the different attempts to explain the differences between the sex ratios. Among these attempts we can find diverse hypotheses that vary from the role of the sex hormones and genetic vulnerability to the biases of medical professionals during the diagnostic process (Goldman, 2013).
Autism spectrum disorder is complex in and of itself but that complexity is only compounded by the comorbid conditions that can come with it. Some of these include sensory processing disorder, obsessive compulsive disorder, and seizures. Understanding the disorder and its comorbid conditions is challenging yet important for parents, medical professionals, and educators.
Because autism symptoms vary in degrees and severity, autism is considered a spectrum disorder; each individual falls somewhere within the spectrum depending on their specific symptoms. Though autism affects a small percentage of children, the number of those affected is on the rise. There are different types of autism including Asperger’s, a mild form of autism in which the individual affected becomes obsessive over interests, and Rett syndrome which affects mostly females and is marked by the loss of communication skills. Asperger’s is on the higher
There is no known single cause of autism. Researchers are investigating a number of possible theories including genetics, heredity, medical problems, problems during pregnancy or delivery, as well as environmental influences. It is widely accepted that it is caused by abnormalities in the brain structure or function. There is evidence from neuropathological studies that autism has its origins in abnormal brain development early in prenatal life which continues postnatally, showing acceleration in brain growth measured by head circumference (Zwaigenbaum, L., Bryson, S., Rogers, T., Roberts, W., Brian, J., & Szatmari, P., 2005). The disorder also seems to have a genetic basis, although researchers have yet to find the specific genes that link to the onset of autism. There could be a cluster of genes that have somehow interfered with normal brain development and function. Studies show that twins of children with autism were more likely to be autistic themselves than the regular population, demonstrating there is a heredity lin...
Gender is a performance according to Judith Butler . All bodies, she claims, are gendered from birth; sometimes even earlier now we can determine sex in the womb . For Butler society dictates ones gender and the individual reinforces that gender through performance . “The deeds make the doer” in Butler’s words; there is no subject prior to performance. Butler’s concept of gender, however, leads us to question: what of those who are incapable of performing the gender ascribed to them? If one is unable to perform are they left genderless, lacking subjectivity and social identity? If no human is without gender , as Butler claims, then where does this leave her theory? Either gender is more than simply performance or one can exist without gender.
“Dr. Michael Dougherty” believes there is a combination between both genetics and environmental factors” (page20). “Dr. Michael Dougherty” believes that chromosome 12 is the main cause to the genetic side of autism. Amino acids which is parts of food protein that cannot be broken if a child has two mutated copies of chromos...
Autism spectrum disorder and Asperger’s syndrome, a higher function branch of autism spectrum disorder, affect many adults in the world. These disorders affect the development of thinking and social skills. Many adults have difficulty leading normal lives due to the effects of autism spectrum disorder and Asperger’s syndrome. They have difficulty in school, at work, and even in the social situations of everyday life. The paper examines how autism spectrum disorder affects adults in fields such as: difficulty with higher education, difficulty with finding and keeping jobs in the labor force, and difficulty with social situations. The paper will be concluded with how society views autism spectrum disorder and what it believes should be done.
Most Autistic children have different abilities and task they can and can not do, It is important to raise awareness for children with Autism. Most people do not realize how many
Autism is a genetic disorder that typically appears during the first three years of life. There has been five chromosomes thought to be directly connected to autism. The disorder is a complex developmental disability. Autism is the result of a neurological disorder that has an effect on normal brain functions, affecting development of the person’s communication and social interaction skills. There are many different ways to classify autism; by difficulties in social interaction, verbal and non-verbal communication and repetitive behavior. Autism appears to have its roots in very early brain development, however most signs of autism become obvious around two and three years old. According to the U.S Centers for Disease and Control and Prevention about 1 and 68 American children are diagnosed with Autism. Studies have showed that autism is four to five times more common in boys than girls. Which is an estimated 1 out of 42 boys are diagnosed with it compared to an estimated 1 out 189 girls are diagnosed with in the United States. Autism rates. There is many different causes linked to Autism. The two main factors that are mainly discussed are that Autism is genetically inherited and autism is established via environmental factors.
As the prevalence of Autism continues to grow rapidly, it is proven fact that Autism is the fastest-growing serious developmental disability in the United States. “On March 27, 2014, this surveillance study identified one in sixty-eight children (one in forty-two boys and one in one-hundred eighty-nine girls) as having Autism Spectrum Disorder (ASD).” (DSM-IV, 2000). Eight-hundred thousand people younger than eighteen years are on record as having Autism Spectrum Disorder in the United States. Most children display abnormalities within the first year of life; although most are diagnosed with Autism between the ages of two and three. Boys are nearly five times more likely than girls to have Autism. However, females with the disorder are more feasible to exhibit serious mental retardation. There are “approximately seventy-five percent of children with Autism are mentally handicapped; meaning their IQ ranges from thirty-five to fifty. According to the Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV, 2000) research suggests that only a small percentage of individuals with Autistic Disorder go on as adults to live and work independently.” ( DSM-IV, 2000)
“Autism is a lifelong developmental disability that affects how someone communicates with, and relates to other people. Autism also affects how a person makes sense of the world around them ”(autism.org). People wonder the causes of this disability, but what they do not know is there has not been an official cause yet determined! Although there hasn’t been an official cause of autism, there are a lot of theories people believe cause autism. One of the main theories is what pills or vitamins women take during their pregnancy. During pregnancy women have to be very careful on what antibiotics or vitamins they take. Sometimes the child can be affected by the pill which leads to problems during birth. “Another major theory is exposure to chemical pollutants, metals, pesticides, etc.” (webmd.). These substances contain a lot of poisons, chemicals, or bacteria that are very dangerous for a fetus to be exposed too. This is why people say pregnant women should just stay away from places where these substances are. But the main theory that many people think causes autism is vaccines. Although vaccines are supposed to prevent disease, people think there is a chemical in them which causes autism, but this theory is false! The cause of autism has not yet been fully determined, but it is not caused by vaccines; it is usually caused by genetics, metabolic or neurological factors, or lastly problems that occurred during birth.
Statistics show that boys are affected 5 times more than girls. According to data, 1 in 68 children are diagnosed with autism. To be more specific, 1 in 42 boys is affected and 1 in 189 girls is affected. There is a higher chance of boys getting autism than girls.
