and Pedcheck (O’Connell & Weeks, 1998) was used to look for Mendelian errors (total N=1814). No Mendelian errors in haplotype assignment were identified. The final sample (N=1128 individuals from 476 families) consisting of all those with data available for H2 haplotype, CSA, and outcome measures included 565 women [mean age 41.0, (SD 8.6)] and 563 men [mean age 43.1, (SD 9.4)]. These individuals almost exclusively report Anglo-Celtic or other European ancestry.
