Renal Tubule and Collecting Duct01:24

Renal Tubule and Collecting Duct

The renal tubule is divided into three parts: the proximal convoluted tubule (PCT), the Loop of Henle (LOH), and the distal convoluted tubule (DCT).
Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
Pleiotropy01:33

Pleiotropy

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,...
Smooth Endoplasmic Reticulum01:21

Smooth Endoplasmic Reticulum

Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...
Skin Diseases and Disorders01:23

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
Huntington Disease l: Introduction01:21

Huntington Disease l: Introduction

Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
Desmosomes01:05

Desmosomes

The term desmosome derives from the Greek words "desmo" and "soma" meaning "adhesion bodies." This structure was first observed during the late 1800s and described as small, dense nodules in the epidermis. Desmosomes are button-like structures that help form an interlinked network of intermediate filaments across the cells. These junctions are  essential to hold cells together under mechanical stress and to maintain tissue integrity. Desmosomes are multi-protein complexes comprising desmosomal...

Summary
This summary is machine-generated.

Hypohidrotic ectodermal dysplasia (HED) is a rare genetic disorder often diagnosed late, with a mean diagnostic period of 14 years. Early diagnosis and genetic counseling are crucial for improving patient quality of life.

Area of Science:

  • Genetics
  • Dermatology
  • Pediatrics

Context:

  • Ectodermal dysplasias are rare inherited disorders affecting ectodermal structures.
  • Hypohidrotic ectodermal dysplasia (HED) presents with characteristic symptoms like hypotrichosis and hypodontia.
  • This study analyzes a series of HED cases to understand its clinical profile.

Purpose:

  • To precisely define the epidemioclinical characteristics of hypohidrotic ectodermal dysplasia (HED).
  • To evaluate diagnostic tools, disease progression, and treatment strategies for HED.
  • To present findings from a 10-case series of HED.

Summary:

  • A retrospective analysis of 10 HED cases (average age 14) revealed a mean diagnostic delay of 14 years.
  • Key features included facial dysmorphy, hypotrichosis, hypodontia, and varying degrees of sweat gland abnormalities.
  • Extra-cutaneous manifestations such as recurrent respiratory and ophthalmologic issues were common.

Impact:

  • Highlights the significant diagnostic delay in HED, often leading to diagnosis in adulthood.
  • Confirms X-linked inheritance in most cases but suggests possible autosomal transmission.
  • Emphasizes the importance of early diagnosis for improved patient quality of life and genetic counseling.
