Overview
General Transcription Factors01:30

General Transcription Factors

Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...
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.

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Lethal Alleles

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

Area of Science:

  • Immunology
  • Molecular Biology
  • Genetics

Background:

  • Agammaglobulinemia is a primary immunodeficiency characterized by a severe reduction in immunoglobulin levels.
  • Early B cell development is critical for a functional adaptive immune system.

Purpose of the Study:

  • To elucidate novel immunological and molecular mechanisms underlying early B cell development arrest.
  • To describe genetic defects causing autosomal recessive agammaglobulinemia.

Main Methods:

  • Genetic analysis of patients with unexplained agammaglobulinemia.
  • Immunological profiling to assess B cell development stages.

Main Results:

  • Identified mutations in Ig beta, a component of the pre-B cell receptor, as a novel cause of human agammaglobulinemia.
  • Described the first two patients with documented Ig beta mutations leading to this condition.

Conclusions:

  • Mutations in Ig beta represent a newly recognized genetic cause of agammaglobulinemia, expanding the known spectrum of defects.
  • These findings enhance understanding of human B cell development and suggest potential gene therapy targets.
