morrow_08_ASD_discovery_cases
Affected individuals from 70 families (52 simplex, 18 multiplex) recruited by Homozygosity Mapping Collaborative for Autism (HMCA) used in CNV analysis. This cohort was selected from an original population of affected individuals from 104 families (79 simplex, 25 multiplex; 82.7% male); 88 of these pedigrees have cousin marriages.
