"On August 15th, the BSRC published a paper in Pediatrics which reexamined the recurrence rate of autism in high risk families. It found that in families with one or more children on the autism spectrum, the chances that a baby sibling will develop autism are around 1 in 5, more than double previous estimates of 1 in 10 to 1 in 30. The rate was much higher among younger brothers (1 in 4) than among younger sisters (1 in 9). In families with more than one older child on the spectrum, 1 in 3 infants eventually developed autism. The severity of the older sibling's autism did not affect the risk to younger brothers or sisters, nor did other family attributes such as parental age, ethnicity, or birth order."
