Insights

Huntington's disease (HD) is a progressive neurogenetic disorder with no current treatments. Research using human molecular genetics aims to find disease-modifying therapies by understanding its causes and identifying drug targets.

Area of Science:

  • Neurogenetics
  • Molecular Biology
  • Pharmacology

Background:

  • Huntington's disease (HD) is a severe, inherited neurodegenerative disorder.
  • First described in the 19th century, HD remains without disease-modifying treatments.
  • HD research has pioneered the use of human molecular genetics.

Purpose of the Study:

  • To leverage human molecular genetic strategies for HD research.
  • To identify the genetic basis of Huntington's disease.
  • To understand the pathogenesis of HD and discover therapeutic targets.

Main Methods:

  • Application of human molecular genetic strategies.
  • Analysis of familial data for genetic linkage.
  • Pathogenesis studies.

Main Results:

  • Identification of disease-causing genes for HD.
  • Elucidation of molecular mechanisms underlying HD pathogenesis.
  • Establishment of rational targets for therapeutic development.

Conclusions:

  • Human molecular genetics is crucial for advancing HD research.
  • Understanding HD genetics and pathogenesis is key to developing treatments.
  • Active family participation is vital for progress in HD research.

Human Genetics

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...

Incomplete Dominance01:43

Incomplete Dominance

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Animal 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...

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...
