Comparing Copy Number Variations and SNPs02:26

Comparing Copy Number Variations and SNPs

Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Genome-wide Association Studies-GWAS

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...

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within the...
Schizophrenia01:17

Schizophrenia

Schizophrenia, a term introduced by Swiss psychiatrist Eugen Bleuler in 1911, describes a severe psychological disorder marked by profound disruptions in attention, thought processes, language, emotion, and interpersonal relationships. The core feature of schizophrenia is psychosis — a state characterized by a fundamental detachment from reality. This disconnection manifests through distorted logic, impaired perception, and atypical behavior, severely affecting the lives of those diagnosed.
Biological Causes of Schizophrenia01:29

Biological Causes of Schizophrenia

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 studies.
Psychological and Sociocultural Causes of Schizophrenia01:29

Psychological and Sociocultural Causes of Schizophrenia

Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

Area of Science:

  • Genetics
  • Psychiatry
  • Molecular Biology

Background:

  • Schizophrenia is a complex psychiatric disorder with a significant genetic component.
  • The KPNB3 gene has been implicated in schizophrenia, but further validation in diverse populations is needed.

Purpose of the Study:

  • To reconfirm the association of the KPNB3 gene with schizophrenia in a Chinese Han population.
  • To investigate the role of specific single nucleotide polymorphisms (SNPs) within KPNB3.

Main Methods:

  • Genotyping of two KPNB3 SNPs (rs2588014 and rs626716) in 304 Chinese Han family trios using PCR-RFLP.
  • Transmission Disequilibrium Test (TDT) and haplotype analysis performed using UNPHASED software.
  • Assessment of Hardy-Weinberg equilibrium for genotypic distributions.

Main Results:

  • Both SNPs were in Hardy-Weinberg equilibrium.
  • Significant allelic association found for SNP rs626716 (P = 0.0023) via TDT.
  • Haplotype analysis revealed a strong disease association (P = 0.0000097).

Conclusions:

  • The study provides further genetic evidence supporting the association of KPNB3 with schizophrenia in the Chinese population.
  • SNP rs626716 and specific haplotypes within KPNB3 are significantly associated with schizophrenia.
