[Genetic aspects of schizophrenia]

Area of Science:

• Genetics
• Psychiatry
• Genomic Medicine

Background:

• Schizophrenia exhibits complex, non-Mendelian inheritance, involving multiple genes.
• Identifying genomic variations linked to schizophrenia endophenotypes holds significant potential for understanding the disease.
• Current understanding points to a polygenic model rather than single-gene determination.

Purpose of the Study:

• To review genetic markers associated with schizophrenia.
• To discuss current analytical methods, including genome-wide association studies (GWAS).
• To highlight genes implicated in schizophrenia risk and their functional polymorphisms.

Main Methods:

• Review of existing literature on schizophrenia genetics.
• Description of genome-wide association studies (GWAS) and other genetic analysis techniques.
• Identification and discussion of specific genes and polymorphisms linked to schizophrenia risk and clinical presentation.

Main Results:

• Several genes with mutations increasing schizophrenia risk have been identified.
• Functional polymorphisms significantly associated with clinical manifestations can serve as genetic markers.
• No single definitive susceptibility gene for schizophrenia has been established.

Conclusions:

• Genetic markers, particularly functional polymorphisms, show promise for understanding schizophrenia.
• Genome-wide association studies (GWAS) are valuable tools in identifying genetic associations.
• Further global research across diverse populations is essential to discover more schizophrenia susceptibility genes.
