We identified one hit for the Compulsive disorders factor, a locus also associated with AN16 (Supplementary Tables 14 and 15). We identified two loci for the Compulsive disorders factor-specific QSNP statistic (Supplementary Table 16), including a locus (rs1906252) with strong opposing effects on AN and TS. We identified 108 hits for the Psychotic disorders factor, 96 of which were in LD with previously reported associations for BIP and SCZ (Supplementary Table 17), and 12 of which were novel relative to the contributing univariate GWASs. The Psychotic disorders factor-specific QSNP statistic revealed six hits, three of which were in LD with hits for ALCH (Supplementary Table 19), including a locus in the well-described Alcohol Dehydrogenase 1B (ADH1B) gene that was significant for factor-specific QSNP for all four factors.
