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 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.

Principles of Pharmacogenetics: Types of Genetic Variants

98
The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...

Sex-linked Disorders01:43

Sex-linked Disorders

111.3K
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.

Animal Mitochondrial Genetics

10.1K
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...

Area of Science:

  • Neurogenetics
  • Movement Disorders

Background:

  • Essential tremor (ET) is a common adult-onset movement disorder with a strong genetic component.
  • Identifying causative genes for ET, both monogenic and complex forms, remains challenging due to clinical and genetic heterogeneity.

Purpose of the Study:

  • To review the challenges and future directions in identifying essential tremor genes.
  • To highlight the need for robust methodologies in ET genetic research.

Main Methods:

  • Literature review of recent genetic discoveries in essential tremor.
  • Discussion of challenges including diagnostic criteria, heterogeneity, and gene validation.

Main Results:

  • Recent gene associations (LINGO1, FUS, TENM4) show promise but require further validation.
  • Reproducibility and pathogenicity of implicated genes are contentious issues.

Conclusions:

  • Future essential tremor genetic studies must employ multi-prong genomic approaches with large sample sizes.
  • Functional in vitro and in vivo studies are crucial for elucidating pathophysiologic mechanisms and developing therapies.
