Locus‐Specific Genetic Associations at the DAOA Gene in Schizophrenia and Bipolar Disorder

Advanced Genetics, Volume 7, Issue 2, June 2026.
This study explores locus‐specific genetic associations at the DAOA gene in schizophrenia (SZ) and bipolar disorder (BD). Using genotype, haplotype, and phenotype analyses, the authors identify a variant (rs2391191) showing associations with both disorders, while another variant (rs1935062) shows no disease association but exploratory links to clinical

Face engagement during infancy predicts later face recognition ability in younger siblings of children with autism [PDF]

, 1969
Face recognition difficulties are frequently documented in children with autism spectrum disorders (ASD). It has been hypothesized that these difficulties result from a reduced interest in faces early in life, leading to decreased cortical specialization
