Bone Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

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,...
Sex-linked Disorders01:43

Sex-linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.
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...

Area of Science:

  • Endocrinology
  • Genetics
  • Metabolic Disorders

Background:

  • Albright hereditary osteodystrophy (AHO) is a rare genetic disorder.
  • It can present with or without pseudohypoparathyroidism, characterized by hormone resistance.
  • Key features include distinctive physical traits and metabolic abnormalities.

Observation:

  • This report focuses on a family with two siblings diagnosed with AHO.
  • The siblings exhibited reduced Gs-alpha activity, a key molecular marker.
  • Clinical evaluation included physical examination, oral manifestations, radiographic assessment, and laboratory tests.

Findings:

  • The siblings presented with characteristic AHO physical features.
  • Laboratory tests revealed hypocalcemia and hyperphosphatemia.
  • Reduced Gs-alpha activity confirmed the diagnosis of AHO.

Implications:

  • This case highlights the importance of recognizing AHO in affected families.
  • Understanding the clinical spectrum and molecular basis is crucial for diagnosis and management.
  • Further research into Gs-alpha activity and its impact on AHO is warranted.
