Genome-wide Association Studies-GWAS

14.5K
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...

Behavioral Genetics and Its Designs

573
Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.
The primary methodologies used in behavior genetics include family studies, twin studies, and adoption studies, each providing unique...

Human Genetics

755
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Polygenic Traits01:18

Polygenic Traits

66.7K
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...

Area of Science:

  • Genetics
  • Bioinformatics
  • Neuroscience

Background:

  • Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder with a significant genetic component.
  • Over 100 ASD risk genes have been identified, but an estimated 1000+ genes likely contribute to ASD risk.
  • Prioritizing candidate genes is essential for discovering novel ASD risk genes.

Purpose of the Study:

  • To develop a novel computational framework for prioritizing autism spectrum disorder (ASD) risk genes.
  • To integrate diverse genomic data types for enhanced ASD gene discovery.

Main Methods:

  • Developed BNScore, a Bayesian model selection framework.
  • Integrated sequencing data, biological annotations, and gene functional networks.
  • Validated performance against benchmark genes and genome-wide association studies.

Main Results:

  • BNScore effectively prioritizes ASD risk genes by integrating multiple data sources.
  • The framework demonstrates superior performance compared to existing methods.
  • Top prioritized genes show specific expression patterns in brain tissues, particularly during fetal development and in specific neuronal types.

Conclusions:

  • BNScore offers a robust and flexible strategy for ASD risk gene prioritization.
  • The integration of sequencing, annotation, and network data significantly enhances gene discovery.
  • This approach has potential applications for identifying risk genes in other complex traits.
