In this context, polygenic risk scores (PRSs) quantifying the additive effects of multiple common genetic variants hold the potential to predict complex diseases and index severity gradients. PRSs for schizophrenia (SZ) and bipolar disorder (BD) were computed using Bayesian regression and continuous shrinkage priors based on the latest SZ and BD genome-wide association studies (Psychiatric Genomics Consortium, third release). Eight well-phenotyped groups (n = 1580; 56% males) were assessed: control (n = 305), lower (n = 117) and higher (n = 113) schizotypy (both groups of healthy individuals), at-risk for psychosis (n = 120), BD type-I (n = 359), BD type-II (n = 96), schizoaffective disorder (n = 86), and SZ groups (n = 384). PRS differences were investigated for binary traits and the quantitative Positive and Negative Syndrome Scale. Both BD-PRS and SZ-PRS significantly differentiated controls from at-risk and clinical groups (Nagelkerke’s pseudo-R2: 1.3–7.7%), except for BD type-II for SZ-PRS. Out of 28 pairwise comparisons for SZ-PRS and BD-PRS, 9 and 12, respectively, reached the Bonferroni-corrected significance. BD-PRS differed between control and at-risk groups, but not between at-risk and BD type-I groups. There was no difference between controls and schizotypy. SZ-PRSs, but not BD-PRSs, were positively associated with transdiagnostic symptomology. Overall, PRSs support the continuum model across the psychosis spectrum at the genomic level with possible irregularities for schizotypy. The at-risk state demands heightened clinical attention and research addressing symptom course specifiers. Continued efforts are needed to refine the diagnostic and prognostic accuracy of PRSs in mental healthcare. 000903471 536__ $$0G:(DE-HGF)POF4-5251$$a5251 - Multilevel Brain Organization and Variability (POF4-525)$$cPOF4-525$$fPOF IV$$x0 000903471 588__ $$aDataset connected to CrossRef, Journals: juser.fz-juelich.de 000903471 7001_ $$00000-0001-9366-8728$$aPapiol, Sergi$$b1 000903471 7001_ $$aTheodoridou, Anastasia$$b2 000903471 7001_ $$aHeekeren, Karsten$$b3 000903471 7001_ $$aGerstenberg, Miriam$$b4 000903471 7001_ $$aWotruba, Diana$$b5 000903471 7001_ $$aBuechler, Roman$$b6 000903471 7001_ $$aHoffmann, Per$$b7 000903471 7001_ $$00000-0002-2786-8200$$aHerms, Stefan$$b8 000903471 7001_ $$aAdorjan, Kristina$$b9 000903471 7001_ $$aAnderson-Schmidt, Heike$$b10 000903471 7001_ $$00000-0001-7301-9157$$aBudde, Monika$$b11 000903471 7001_ $$00000-0001-6745-9834$$aComes, Ashley L.$$b12 000903471 7001_ $$aGade, Katrin$$b13 000903471 7001_ $$aHeilbronner, Maria$$b14 000903471 7001_ $$00000-0001-7135-762X$$aHeilbronner, Urs$$b15 000903471 7001_ $$00000-0003-0930-4214$$aKalman, Janos L.$$b16 000903471 7001_ $$aKlöhn-Saghatolislam, Farahnaz$$b17 000903471 7001_ $$aReich-Erkelenz, Daniela$$b18 000903471 7001_ $$aSchaupp, Sabrina K.$$b19 000903471 7001_ $$aSchulte, Eva C.$$b20 000903471 7001_ $$aSenner, Fanny$$b21 000903471 7001_ $$aAnghelescu, Ion-George$$b22 000903471 7001_ $$aArolt, Volker$$b23 000903471 7001_ $$aBaune, Bernhard T.$$b24 000903471 7001_ $$00000-0002-0623-3759$$aDannlowski, Udo$$b25 000903471 7001_ $$aDietrich, Detlef E.$$b26 000903471 7001_ $$aFallgatter, Andreas J.$$b27 000903471 7001_ $$aFigge, Christian$$b28 000903471 7001_ $$aJäger, Markus$$b29 000903471 7001_ $$aJuckel, Georg$$b30 000903471 7001_ $$00000-0001-7015-3860$$aKonrad, Carsten$$b31 000903471 7001_ $$00000-0001-7884-4500$$aNieratschker, Vanessa$$b32 000903471 7001_ $$aReimer, Jens$$b33 000903471 7001_ $$00000-0001-5964-4087$$aReininghaus, Eva$$b34 000903471 7001_ $$aSchmauß, Max$$b35 000903471 7001_ $$aSpitzer, Carsten$$b36 000903471 7001_ $$avon Hagen, Martin$$b37 000903471 7001_ $$00000-0003-1492-5330$$aWiltfang, Jens$$b38 000903471 7001_ $$aZimmermann, Jörg$$b39 000903471 7001_ $$aGryaznova, Anna$$b40 000903471 7001_ $$aFlatau-Nagel, Laura$$b41 000903471 7001_ $$aReitt, Markus$$b42 000903471 7001_ $$aMeyers, Milena$$b43 000903471 7001_ $$aEmons, Barbara$$b44 000903471 7001_ $$aHaußleiter, Ida Sybille$$b45 000903471 7001_ $$aLang, Fabian U.$$b46 000903471 7001_ $$aBecker, Thomas$$b47 000903471 7001_ $$aWigand, Moritz E.$$b48 000903471 7001_ $$00000-0002-1571-1468$$aWitt, Stephanie H.$$b49 000903471 7001_ $$aDegenhardt, Franziska$$b50 000903471 7001_ $$0P:(DE-Juel1)186755$$aForstner, Andreas J.$$b51 000903471 7001_ $$00000-0002-5236-6149$$aRietschel, Marcella$$b52 000903471 7001_ $$aNöthen, Markus M.$$b53 000903471 7001_ $$00000-0002-2917-5889$$aAndlauer, Till F.
