Ultra-rare coding variants in schizophrenia risk genes are associated with longitudinal phenotypic differences across psychotic disorders

Anders J. Kämpe, Julia Sealock, Evan Jeffrey Giangrande…·Olli P. H. Pietiläinen

This study identifies ultra-rare damaging variants in schizophrenia risk genes and shows they are associated with earlier hospitalizations, greater childhood adversity, and poorer neuropsychological outcomes across psychotic disorders.

Functional characterization of six SLCO1B1 (OATP1B1) variants observed in Finnish individuals with a psychotic disorder

Katja Häkkinen, Wilma Kiander, Heidi Kidron…·the SUPER-Finland researchers listed in the Acknowledgements

The paper investigates six rare SLCO1B1 variants in Finnish individuals with psychosis, finding one variant causes loss-of-function and reduced OATP1B1 protein expression.

Implementation of CYP2D6 copy-number imputation panel and frequency of key pharmacogenetic variants in Finnish individuals with a psychotic disorder

Katja Häkkinen, Johanna I. Kiiski, Markku Lähteenvuo…·Ari Ahola‐Olli

The paper constructs a CYP2D6 copy-number imputation panel and reports pharmacogenetic variant frequencies in Finnish individuals with psychosis, showing high imputation accuracy but limited clinical utility.
