Biological Causes of Schizophrenia01:29

Biological Causes of Schizophrenia

853
Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.
Genetic Factors in Schizophrenia
The genetic basis of schizophrenia is strongly supported by family and twin...

Genome-wide Association Studies-GWAS

16.2K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Area of Science:

  • Genomics
  • Neuroscience
  • Bioinformatics

Background:

  • Schizophrenia (SCZ) diagnosis relies on subjective clinical experience.
  • Objective and quantitative diagnostic methods for SCZ are needed.
  • Gene expression analysis shows promise for neurological disease diagnosis.

Purpose of the Study:

  • To develop and validate a machine learning model for schizophrenia diagnosis using whole blood gene expression data.
  • To identify key differentially expressed genes associated with schizophrenia.
  • To assess the diagnostic accuracy and potential clinical utility of the proposed model.

Main Methods:

  • Collected whole blood gene expression data from 152 SCZ patients and 138 controls across four studies.
  • Applied correlation-based feature selection (CFS) to identify 103 differentially expressed 'feature genes'.
  • Developed a diagnostic model using CFS and validated it through 10-group cross-validation.

Main Results:

  • The developed model achieved nearly 100% classification accuracy for schizophrenia.
  • Identified 103 significantly differentially expressed genes between SCZ patients and controls.
  • Enrichment analysis revealed feature genes are involved in Parkinson's disease, oxidative phosphorylation, and TGF-beta signaling pathways.

Conclusions:

  • Gene expression analysis in whole blood, coupled with machine learning, can provide a highly accurate diagnostic tool for schizophrenia.
  • The identified feature genes and pathways offer insights into the molecular mechanisms of SCZ.
  • This approach could lead to more objective and quantitative clinical diagnosis of schizophrenia.
