Cancer-Critical Genes II: Tumor Suppressor Genes

10.5K
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...

The Retinoblastoma Gene

5.0K
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,...

    Area of Science:

    • Oncology
    • Genetics
    • Medical Diagnosis

    Background:

    • Hereditary breast cancer syndromes present diversely, extending beyond BRCA1/BRCA2-associated Hereditary Breast and Ovarian Cancer (HBOC).
    • Accurate risk assessment necessitates a comprehensive review of personal and family medical histories.
    • Clinicians must recognize the spectrum of hereditary cancer syndromes to ensure timely diagnosis and intervention.

    Observation:

    • Failure to diagnose rare hereditary breast cancer syndromes can result in missed opportunities for preventative management and screening.
    • Effective management of hereditary breast cancer requires a multidisciplinary team approach.
    • Cancer gene panels offer diagnostic benefits but may yield incidental findings, unexpected diagnoses, or inconclusive results.

    Findings:

    • Genetic testing, particularly with cancer gene panels, can reveal complex genetic information.
    • Comprehensive pre- and post-test genetic counseling is vital for patients undergoing genetic testing.
    • Informed decision-making regarding genetic testing requires understanding the implications of various genetic syndromes.

    Implications:

    • Early and accurate identification of hereditary cancer syndromes enables proactive management and screening strategies.
    • Genetic testing, when coupled with thorough counseling, empowers patients, families, and physicians in medical decision-making.
    • A team-based approach enhances the identification and management of individuals with hereditary breast cancer syndromes.
