Mutagenicity and Carcinogenicity01:25

Mutagenicity and Carcinogenicity

2.2K
Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...

Cancer-Critical Genes I: Proto-oncogenes

12.2K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Genetic Screens02:46

Genetic Screens

5.9K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Principles of Pharmacogenetics: Types of Genetic Variants

121
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...

Area of Science:

  • Oncology
  • Genetics
  • Medical Diagnostics

Background:

  • Hereditary breast cancer diagnosis relies on genetic testing and established clinical guidelines.
  • Advances in genetic testing have improved the identification of inherited cancer predispositions.

Observation:

  • A family presented with multiple early-onset breast cancer cases.
  • Some cases were linked to a pathogenic BRCA1 E143X nonsense mutation, while others were not.

Findings:

  • The family's presentation illustrated complexities in strictly adhering to current genetic testing guidelines.
  • Clinical judgment is essential for interpreting results when a family history is mixed.

Implications:

  • This case underscores the need for experienced clinical evaluation beyond rigid guideline application.
  • Personalized approaches are vital in hereditary cancer diagnosis and management.
