I have this belief that Autism might have run in our family. It might be in our genes. Two in our family were already diagnosed with Autism. My nephew was diagnosed with severe autism when he was 7 years old. He displayed all the early signs of autism at a tender age of 3. He has problems with speaking and communicating properly. He walks in an awkward manner and does not behave most of the time. My son likewise displayed the early signs at the same age and was diagnosed at the age of 5. There is also a possibility that my niece also has autism because of the signs that she is currently manifesting. She also has speech, communication and behavioural problems. She cannot speak properly mumbles most of the time. Her behaviour is quite erratic and screams most of the time when frustrated. She is hyperactive and cannot stay in one place for a long time. I firmly believe that this is not a coincidence but a probability of heredity being a causative factor to the growing number of people affected with autism.
According to research, family genes might have a probable link to Autism. Recent studies have highlighted an important difference in the types of families that have members with Autism Spectrum Disorder(ASD). When there is one member diagnosed with ASD and no one in the extended family has a diagnosis it is referred to as ‘simplex’ autism. The probable cause might be due to the one-off change during the formation of gametes. This difference can occupy for 10% of all people diagnosed with ASD. But when there is more than one member of the extended family has a diagnosis or several members have very high levels of autistic traits, they are referred to as ‘multiplex” families. There is also specific genetic difference passed down through generations, that might be the basis of the increased incidence of ASD in these families. There is also those well-known genetic difference of Autism such as Fragile X syndrome, Rett syndrome, Tuberous sclerosis, and the Smith-Lemli-Opitz syndrome. We also need to consider these genetic differences to potentially be included in the genetic testing of ASD.
