In general, the risk of having a child with autism spectrum disorder (ASD) is about 1 in 68, or 1.5%. But the risk goes up for families who already have a child with ASD. If a family has one child with ASD, the chance of the next child having ASD is about 20%. If the next child is a boy, the risk is 26%, whereas if it’s a girl the risk is 10%. About 47% of families had more than one child with autism. Currently if a child has a birth defect or autism, the emerging trend is to perform whole exome sequencing to identify genetic mutations. These mutations overwhelmingly come from the father, because sperm cells but not egg cells continue to divide through the life of adults. Once the mutation is identified, the diagnosis can be made in the child, but the parents are left wondering if this genetic event could recur in future children. Currently there is no genetic assessment of sperm available commercially, and no publications on the application of using sperm as a way to assess risk of childhood disease, nor is there a risk assessment available for couples that have had a child with a genetic disease due to de novo genetic mutation.
