Heritability of condition 33 per cent higher than previously thought, according to research
Quote:
Reanalysis of data from a previous study on the familial risk of Autism Spectrum Disorder (ASD) estimates the heritability to be 83 per cent, according to a study published by JAMA.
Prior studies have found that autism aggregates in families, but heritability was previously estimated to be around 50 per cent.
To define presence or absence of autism, the previous study used a data set created to take into account time-to-event effects in the data, which may have reduced the heritability estimates.
Using the same underlying data from this study, Sven Sandin of the Icahn School of Medicine at Mount Sinai, New York, and colleagues used an alternative method to calculate the heritability.
The study included a group of children born in Sweden 1982 through 2006, with follow-up for autism through December 2009.
The analysis included 37,570 twin pairs, 2,642,064 full sibling pairs, and 432,281 maternal and 445,531 paternal half-sibling pairs
