Pleiotropy01:33

Pleiotropy

43.1K
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,...

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

4.6K
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,...

Genomic Imprinting and Inheritance02:30

Genomic Imprinting and Inheritance

36.7K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Abnormal Proliferation02:23

Abnormal Proliferation

5.0K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Cancers Originate from Somatic Mutations in a Single Cell02:21

Cancers Originate from Somatic Mutations in a Single Cell

14.5K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

Area of Science:

  • Gastroenterology and Oncology
  • Genetics and Hereditary Syndromes

Background:

  • Colorectal cancer (CRC) is a significant health concern, with 3-5% of cases linked to inherited cancer syndromes.
  • Awareness and referral for genetic testing in high-risk individuals remain low despite decreasing costs.

Purpose of the Study:

  • To review clinical features, genetics, and management of hereditary gastrointestinal (GI) polyposis syndromes.
  • To highlight the importance of timely diagnosis for hereditary polyposis syndromes.

Main Methods:

  • Review of clinical features, genetics, and management strategies for key GI polyposis syndromes.
  • Analysis of recent advancements in endoscopic surveillance and chemoprevention.

Main Results:

  • Enhanced endoscopic techniques (high-definition, chromoendoscopy, cap-assisted) improve lesion detection.
  • Chemoprevention trials show promise, but long-term data is pending.
  • New polyposis genes have been identified, and updated surveillance guidelines are available.

Conclusions:

  • Timely recognition of hereditary GI polyposis syndromes is essential for effective patient and family management.
  • Comprehensive endoscopic surveillance and adherence to updated guidelines can prevent GI cancer and detect early-stage disease.
