Segregation of multiple variants including a sequence variant in AKAP9 and a copy number variant in NRXN1 in a multi-generation pedigree. Pedigree 5 has nine children affected with autism. A link between this pedigree and another high-risk autism pedigree is indicated by the blue box. Sequence variants identified in the family are shown in the black boxes. CNVs identified in four individuals  are shown in red boxes. Pedigree symbols are described in the legend for Figure 2. Odds ratios for the variants observed in the case/control study are shown in parentheses. Variants with no odds ratio were observed only in high-risk families. All family members were tested for all variants unless no DNA was available. Individuals with no available DNA are indicated.
