First, we used a pairwise GWAS analysis to classify variants as associated with only depression, with only Neu or with both. Second, we estimated partial genetic correlations to test whether the depression's genetic link with other phenotypes was explained by shared overlap with Neu.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291719002629_sec_a3\" sec-type=\"results\"><jats:title>Results<\/jats:title><jats:p>We found evidence that most genomic regions (25\/37) associated with depression are likely to be shared with Neu. The overlapping common genetic variance of depression and Neu was genetically correlated primarily with psychiatric disorders. We found that the genetic contributions to depression, that were not shared with Neu, were positively correlated with metabolic phenotypes and cardiovascular disease, and negatively correlated with the personality trait conscientiousness. After removing shared genetic overlap with Neu, depression still had a specific association with schizophrenia, bipolar disorder, coronary artery disease and age of first birth. Independent of depression, Neu had specific genetic correlates in ulcerative colitis, pubertal growth, anorexia and education.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291719002629_sec_a4\" sec-type=\"conclusions\"><jats:title>Conclusion<\/jats:title><jats:p>Our findings demonstrate that, while genetic risk factors for depression are largely shared with Neu, there are also non-Neu-related features of depression that may be useful for further patient or phenotypic stratification.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s0033291719002629","type":"journal-article","created":{"date-parts":[[2019,10,2]],"date-time":"2019-10-02T10:54:15Z","timestamp":1570013655000},"page":"2526-2535","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":40,"title":["Genetic stratification of depression by neuroticism: revisiting a diagnostic tradition"],"prefix":"10.1017","volume":"50","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3599-6018","authenticated-orcid":false,"given":"Mark J.","family":"Adams","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6005-1972","authenticated-orcid":false,"given":"David M.","family":"Howard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7306-3008","authenticated-orcid":false,"given":"Michelle","family":"Luciano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7745-6351","authenticated-orcid":false,"given":"Toni-Kim","family":"Clarke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gail","family":"Davies","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"W.
