Incomplete Dominance01:43

Incomplete Dominance

31.4K
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.

Pleiotropy01:33

Pleiotropy

43.7K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Pigmentation01:19

Pigmentation

4.8K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Polygenic Traits01:18

Polygenic Traits

69.8K
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...

Human Genetics01:28

Human Genetics

1.8K
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...

Area of Science:

  • Immunology
  • Genetics
  • Dermatology

Background:

  • Vitiligo is a complex autoimmune disease.
  • Multiple genetic risk factors and environmental triggers contribute to vitiligo.
  • Genomewide association studies (GWAS) have identified approximately 50 genetic loci associated with vitiligo risk.

Purpose of the Study:

  • To elucidate the genetic and immunological underpinnings of vitiligo.
  • To identify specific genes and DNA variants contributing to vitiligo susceptibility.
  • To understand the complex interplay between the immune system and melanocytes in vitiligo pathogenesis.

Main Methods:

  • Genomewide association studies (GWAS).
  • Identification of genetic loci, genes, and DNA sequence variants.
  • Analysis of gene functions related to immune regulation, apoptosis, and melanocyte biology.

Main Results:

  • Approximately 50 genetic loci contributing to vitiligo risk have been discovered.
  • Genes identified at susceptibility loci are involved in immune regulation, cellular apoptosis, and melanocyte function.
  • Evidence points to a complex autoimmune mechanism in vitiligo.

Conclusions:

  • Vitiligo pathogenesis involves a intricate relationship between immune system programming and function.
  • Melanocyte autoimmune targeting and immune response dysregulation are key factors in vitiligo.
  • Further research is needed to fully elucidate the specific biologic mechanisms underlying vitiligo.
