Doctors recently learned something very surprising;
siblings with autism are more different than they are similar. They do not have
the same risk factors for the disease and they are very unique and distinct in
their behaviors and personalities, just like any other siblings. Through whole-genome sequencing, scientists
were able to analyze genetic material from 85 families with two autistic
children.
Scientists concluded that there were about 100 mutations
that could cause autism and only 30 percent of the 85 siblings tested had the
same mutations. As was expected, the
siblings sharing mutations were more similar in their behaviors than those who
did not. These findings disqualify the common thought that autism is the same
(or close to it) in all of those diagnosed.
Even those that are closely related have a small chance of having the
same variation of autism.
I think that this is a very interesting find. Not many people know about all of the
different kinds of autism affect people in this world. In my opinion, these scientists are going to
have to continue to research families with multiple cases of autism to make
sure these findings are legible. But for
right now, this is a good start to give people a better understanding of
autism.
Interesting, i would have thought it would have been caused by similar or the same mutations.
ReplyDeleteI feel like this makes sense because each birth is another separate joining between a different egg and sperm. It would be interesting if autistic twins did not share the same risk factors.
