^a Family 3524, with two affected siblings with an apparent de novo SHANK3 deletion, was part of another cohort and was thus not included here. In addition, this family’s deletion was previously reported in Sebat et al. [5].
^b 299 patients from deCODE (Iceland); subjects from AGRE and Boston Children’s Hospital overlap other studies and were not included here.
^c One family (2072) was already reported in Sebat et al. [5] (89-3524-100) and Moessner et al. [6] (3524), and was not included here.
