Pleiotropy01:33

Pleiotropy

31.2K
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,...

Microtubules in Signaling01:22

Microtubules in Signaling

1.5K
The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...

Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

2.1K
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Summary
This summary is machine-generated.

Tuberous sclerosis patients frequently develop hamartomatous colonic polyps, some with unique structures. This finding suggests colonic endoscopy aids tuberous sclerosis diagnosis, especially in mild or incomplete cases.

Area of Science:

  • Gastroenterology
  • Neurology
  • Genetics

Background:

  • Tuberous sclerosis (TS) is a genetic disorder characterized by benign tumors in multiple organs.
  • Gastrointestinal manifestations of TS are less common but can include polyps.
  • The spectrum of gastrointestinal polyps in TS patients requires further investigation.

Purpose of the Study:

  • To investigate the prevalence and characteristics of gastrointestinal polyps in patients with tuberous sclerosis.
  • To explore the potential diagnostic utility of colonic endoscopy in identifying TS, particularly forme fruste or incomplete presentations.

Main Methods:

  • Consecutive case series of twelve patients diagnosed with tuberous sclerosis.
  • Clinical evaluation including neurological assessment.
  • Colonoscopy to identify and characterize colonic polyps.

Main Results:

  • Nine out of twelve TS patients had colonic polyps.
  • Polyps included hamartomas (5 patients), adenomatous polyps (3 patients), and mixed types (1 patient).
  • Hamartomatous polyps showed variations, including neural and angiomatous structures; some occurred in patients without neurological symptoms.

Conclusions:

  • Hamartomatous colonic polyps are a significant finding in tuberous sclerosis patients.
  • Tuberous sclerosis should be considered in the differential diagnosis of hamartomatous colonic polyps.
  • Colonic endoscopy may serve as a valuable adjunctive diagnostic tool for tuberous sclerosis, especially in incomplete forms.
