Schizophrenia is a heritable neurocognitive disorder affecting about 1% of the population,
and usually has an onset age at around 21–25 in males and 25–30 in females. Recent …

Schizophrenia (SCZ) is a complex disorder that typically arises in late adolescence or early
adulthood. Age at onset (AAO) of SCZ is associated with long-term outcomes of the disease …

Schizophrenia is a genetically and clinically heterogeneous disorder. Genetic risk factors for
the disorder may differ between the sexes or between multiply affected families compared to …

Schizophrenia has substantial variation in symptom severity, course of illness, and overall
functioning. Earlier age of onset (AOO) is consistently associated with negative outcomes …

We performed a genome‐wide association analysis to identify genetic variants influencing
age at onset (AAO) and examine gene× gender interactions for AAO in schizophrenia (SCZ) …

Early onset schizophrenia (EOS, defined as first onset of schizophrenia before age 18) is a
rare form of schizophrenia (SCZ). Though genome-wide association studies (GWASs) have …

An earlier age at onset (AAO) has been associated with greater genetic loadings in
schizophrenia. This study aimed to identify modifier loci associated with an earlier AAO of …

Age of onset is the single most important characteristic of schizophrenia that could yield
clues to its origin. To identify the age of onset, however, the onset of the pathological …

Background Whether paternal age effect on schizophrenia is a causation or just an
association due to confounding by selection into late parenthood is still debated. We …

Schizophrenia is a genetically complex illness with heterogeneous clinical presentation,
including variable age of onset. In this study, the heritability, or proportion of variation in age …
