Insights

This report details a rare case of juvenile Huntington's disease starting at age seven. Autosomal dominant inheritance was observed, highlighting the importance of family history in diagnosing this rare neurological disorder.

Area of Science:

  • Neurology
  • Genetics
  • Pediatrics

Background:

  • Juvenile Huntington's disease (JHD) is a rare, severe form of Huntington's disease.
  • Onset typically occurs before age 20, presenting distinct clinical features compared to adult-onset HD.
  • Genetic factors and inheritance patterns are crucial for understanding JHD.

Purpose of the Study:

  • To report a rare case of JHD with early onset.
  • To emphasize the diagnostic significance of family history in JHD.
  • To contribute to the understanding of JHD's autosomal dominant inheritance pattern.

Main Methods:

  • Case report of a pediatric patient with suspected Huntington's disease.
  • Detailed clinical evaluation and neurological examination.
  • Pedigree analysis to trace inheritance patterns.

Main Results:

  • The patient presented with symptoms at seven years of age.
  • Autosomal dominant inheritance was confirmed through family history.
  • Three paternal relatives had previously died from a similar disease, supporting the diagnosis.

Conclusions:

  • Early-onset JHD is rare but critical to diagnose.
  • A thorough family history is indispensable for diagnosing JHD.
  • Autosomal dominant inheritance is a key characteristic of this case and JHD overall.

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.
Lysosomal Hydrolases01:22

Lysosomal Hydrolases

Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Alzheimer Disease ll: Pathophysiology

Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...

Parkinson Disease ll: Pathophysiology

Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...
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,...
