“Genes Controlling Affiliative Behavior as Candidate Genes for Autism”

Summary

In “Genes Controlling Affiliative Behavior as Candidate Genes for Autism,” the scientists are researching for specific genes that can cause Autism Spectrum Disorder. Autism Spectrum Disorder (ASD) is a disorder in neuron development. The cause of ASD is unknown. One of the common features of ASD is lack of affiliative behavior, which includes impaired social, linguistic and, motor skill. It has been said that certain genes can cause ASD but, they have not discovered yet. There are also some known environmental factors that can cause Autism-like Symptom. As of May 2008 only 10% of all ASD cases have known cause. There are six genes (OXT, OXTR, PRL, PRLR, DBH, AND FOSB) scientists believe have some influence on maternal and affiliative behavior.
In this study DNA samples have taken from Autistic children and their families. The six genes are separated for further study. The result shows that there are some genes, PRL, PRLR, and OXTR, involved in developing affiliative behaviors.

Personal Response

In my opinion it is great that they have discovered at least something responsible for the behavior noted in ASD children. But they should consider some factors that have impact on those genes. We also need to look at environment those children live in. Maybe it was environmental factor that have impact on genes. It would be good if scientists can develop a test that can be done before baby was born to see any sign of something going wrong with the genes causing ASD.
