A individual sperm donor is the biologic founding father of at least 12 child who all developedautism — an sinful case that actuate one fair sex to action her sperm cell bank , according to news account .
The guinea pig come to visible radiation when the cleaning woman , Danielle Rizzo of Illinois , was researching treatments for her two sons , who both have autism , according toThe Washington Post . Both sons were conceived with sperm from the same donor , and Rizzo was appalled to discover that other mother who used the same donor also had sons with autism , the Post account .
Rizzo was told that the likelihood of all these refer children have got autism by opportunity was like all the mother " open up a lexicon and point to the same letter of the same countersign on the same page at the same time , " she tell the Post .
That means a mutation in the donor ’s sperm cell was likely responsible . But is there a undivided " autism gene ? "
In short , no : There are C ofgenetic variations tied to autismspectrum disorder , according to theNational Institutes of Health ( NIH ) . In most vitrine , these mutant increase a individual ’s risk of autism , but they do n’t designate someone to develop the condition . In other Logos , genes typically recreate only a partial role in the risk of developing autism , with environmental factors , such as the parents ' ages and birth complicatedness , contributing as well .
But in rare cases , genetic mutations are call back to be the main cause of autism . Only about 2 % to 4 % of people with autism have these sport , according to the NIH .
" We call autism one affair , but it ’s unlike in every person . In some , it ’s all about the factor . Some it ’s a combination of cistron and the surroundings . Some people , it ’s unknown , " Dr. Wendy Chung , a professor of pediatric music at Columbia University , secern the Post .
study of Rizzo ’s minor found that they had two mutations tied to autism in genes called MBD1 and SHANK1 .
Most reproductive clinic tryout for several hundred genetic conditions , but there is no test for autism , The Post reported .
In Rizzo ’s lawsuit , she alleged that the bestower ’s visibility had false information . For example , she tell that the donor did not have a college degree , as the profile listed , and that he had beendiagnosed with ADHD , which was pretermit from the profile , the Post cover . She settled the cause in March for $ 250,000 .
