Summary
Genetic research on stroke risk is advancing, but Indigenous Pacific Islanders in Hawai'i face disparities due to underrepresentation. Addressing these biases is crucial for equitable genetic medicine.
Area of Science:
- Genetics
- Public Health
- Epidemiology
Background:
- Stroke is a leading global cause of death with heritable risk factors.
- Genome-wide association studies (GWAS) are identifying genetic loci for stroke.
- Indigenous populations in Hawai'i experience disproportionately high stroke mortality and earlier onset.
Purpose of the Study:
- To highlight scientific biases affecting Indigenous Pacific Islanders in stroke genetics research.
- To discuss the underrepresentation of these communities in genetic studies.
- To present community-based initiatives addressing these disparities.
Main Methods:
- Review of existing literature on stroke genetics and health disparities.
- Analysis of ancestral representation in large-scale genetic studies.
- Case studies of community-led research collaborations.
Main Results:
- Genetic discoveries for stroke risk are not equitably benefiting all populations.
- Indigenous Pacific Islanders are underrepresented in current stroke genetics research.
- Exclusion from genetic discoveries limits access to precision medicine.
Conclusions:
- Scientific biases in genetics research perpetuate health disparities.
- Community engagement is vital for inclusive and equitable research.
- Addressing underrepresentation is essential for advancing precision medicine for all populations.

01:09Mutation, Gene Flow, and Genetic Drift
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).Mechanisms of Genetic VariationThe original sources of genetic variation are mutations,...
02:39Gene Flow
Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.
02:59Animal Mitochondrial Genetics
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...
01:11Genome-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.

01:29Pharmacogenomics: Identification of New Drug Targets
Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
01:21Huntington 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,...
