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...
Huntington Disease l: Introduction01:21

Huntington Disease l: Introduction

Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
Sex-linked Disorders01:43

Sex-linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.
Cardiomyopathy III: Hypertrophic Cardiomyopathy01:29

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Summary

Cluster headache (CH) patients show higher rates of smoking and frequent alcohol consumption compared to their relatives. These lifestyle factors may interact with genetic predispositions in CH development.

Area of Science:

  • Neurology
  • Genetics
  • Epidemiology

Background:

  • Cluster headache (CH) is a debilitating neurological disorder.
  • Previous studies suggest demographic differences between CH patients and the general population, including smoking habits.

Purpose of the Study:

  • To investigate demographic differences in CH patients with a family history and their relatives.
  • To explore potential gene-environment interactions in CH.

Main Methods:

  • A postal questionnaire was administered to CH patients and their first- and second-degree relatives.
  • Data from 83 subjects (42 CH patients, 41 relatives) from 23 families were analyzed.

Main Results:

  • CH patients exhibited significantly higher rates of current or former smoking and frequent alcohol intake.
  • Differences in head trauma history were observed, with some trauma occurring after CH onset.
  • CH patients were more likely to be employed full-time.

Conclusions:

  • Demographic patterns in smoking, alcohol consumption, and head trauma observed in CH patients and relatives align with prior research.
  • Findings suggest potential gene-environment interactions, personality-lifestyle factors, or a combination thereof in CH pathogenesis.
