To define presence or absence of ASD, the 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, Ph.D., of the Icahn School of Medicine at Mount Sinai, New York, and colleagues used an alternate method (used by previous studies in the field) to calculate the heritability of ASD.  Read more…
