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...

This study introduces a new Bayesian method for disease mapping to identify localized spatial patterns and risk boundaries in urban areas. The approach enhances disease risk identification in complex geographical settings.

Area of Science:

  • Spatial epidemiology
  • Geographic Information Systems (GIS)
  • Biostatistics

Background:

  • Disease mapping aims to identify elevated disease risk areas using spatial patterns.
  • Traditional Bayesian hierarchical models assume global spatial smoothness, which may not capture complex urban risk variations.
  • Urban environments often exhibit localized spatial structures and distinct risk boundaries between adjacent populations.

Purpose of the Study:

  • To propose and evaluate a novel approach for capturing localized spatial structure in disease risk.
  • To identify geographical boundaries where disease risk profiles change abruptly.
  • To improve disease mapping accuracy in complex urban settings.

Main Methods:

  • Development of a Bayesian hierarchical model incorporating localized spatial effects.

Identification of Disease-related Spatial Covariance Patterns using Neuroimaging Data

Published on: June 26, 2013

  • Simulation studies to test the effectiveness of the proposed approach in identifying spatial patterns and boundaries.
  • Application to lung cancer incidence data in Greater Glasgow, UK (2001-2005).

    • Main Results:

    • The proposed method effectively captures localized spatial variations in disease risk.
    • The approach successfully identifies boundaries between areas with differing risk profiles.
    • Analysis of lung cancer data demonstrates the practical utility of the method in a real-world urban setting.

    Conclusions:

    • The novel Bayesian approach provides a more nuanced understanding of spatial disease risk in urban areas.
    • This method enhances the identification of localized risk patterns and critical boundaries for public health interventions.
    • The findings have implications for targeted public health strategies and resource allocation in complex geographical regions.
