There appears to be a role for the use of Fragile X studies, High Resolution Chromosomal studies and Chromosomal Microarray studies as part of an initial evaluation on children demonstrating Autistic-like behavior with or without developmental delay.

Many surveys revealed cytogenetically visible chromosomal anomalies in 7.4% of autistic patients, among the most consistent cytogenetic findings are fragile-x and duplication of maternal chromosome 15q11–13 [4]. Environmental component is another important aspect of research in autism.

Mutations in two other X chromosome genes, neuroligin 3 (NLGN3) and neuroligin 4 (NLGN4X), are also associated with autism. Mutations in genes on the X chromosome may explain the increased prevalence of autism in boys compared with girls. In the new study, researchers sought the genetic cause of severe autism in three boys from a large extended family.

An extra copy of a stretch of genes on chromosome 22 may contribute to autism, according to the first study to carefully characterize a large group of individuals who carry this duplication 1. The doubling can also lead to medical complications, such as vision or heart problems.

Autism And Chromosomes A process called linkage analysis is used to identify “genetic hotspots” or chromosome areas having defective genes related to autism, as stated by CPEA investigators who are working with researchers from around the world.

Specifically, they found preliminary data suggesting a paternal effect on chromosome 7 and a maternal effect on chromosome 15. Genetic imprinting has recently been shown to be involved in several...

The heritability of autism is the proportion of differences in expression of autism that can be explained by genetic variation; if the heritability of a condition is high, then the condition is considered to be primarily genetic. Autism has a strong genetic basis, although the genetics of autism are complex and it is unclear whether autism spectrum disorder (ASD) is explained more by multigene ...

In addition to genetic variations that are inherited and are present in nearly all of a person’s cells, recent research has also shown that de novo, or spontaneous, gene mutations can influence the risk of developing autism spectrum disorder.

After receiving the results, a few of the parents were able to find other families affected by the same rare mutation. As genetic testing for autism becomes common, families are forming groups that can offer support as well as provide an entrée for research into autism subtypes. The tests did prompt some negative emotions and confusion, however.

FAQ
🏥
Diagnosing autism spectrum disorder (ASD) can be difficult because there is no medical test, like a blood test, to diagnose the disorder. Doctors look at the child’s developmental history and behavior to make a diagnosis. ASD can sometimes be detected at 18 months or younger. By age 2, a diagnosis by an experienced professional can be considered ...

🏥
Autism spectrum disorder (ASD) is a developmental disability that can cause significant social, communication and behavioral challenges. There is often nothing about how people with ASD look that sets them apart from other people, but people with ASD may communicate, interact, behave, and learn in ways that are different from most other people.
🏥
About 1 in 54 children has been identified with autism spectrum disorder (ASD) according to estimates from CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network.
