Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

10.2K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Incomplete Dominance

32.9K
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Huntington Disease l: Introduction01:21

Huntington Disease l: Introduction

13
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...

Hepatic Encephalopathy01:29

Hepatic Encephalopathy

18
DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic...

Area of Science:

  • Veterinary Neurology
  • Canine Genetics
  • Neurodegenerative Diseases

Background:

  • Hereditary ataxias encompass a spectrum of neurodegenerative disorders characterized by progressive or episodic cerebellar ataxia in dogs.
  • Numerous distinct hereditary ataxia disorders have been identified across various purebred dog breeds, with some breeds exhibiting multiple conditions, complicating diagnosis.
  • The rapid pace of mutation discovery for these disorders offers new avenues for clinical intervention.

Purpose of the Study:

  • To review the current understanding of hereditary ataxias in purebred dogs.
  • To highlight the diagnostic challenges posed by multiple ataxia disorders within single breeds.
  • To emphasize the importance of genetic mutation identification for the prevention, diagnosis, and treatment of canine hereditary ataxias.

Main Methods:

  • Literature review of hereditary ataxia disorders in dogs.
  • Analysis of reported genetic mutations associated with canine cerebellar ataxias.
  • Synthesis of clinical signs and breed predispositions.

Main Results:

  • A wide array of hereditary ataxia disorders exist in purebred dogs.
  • Genetic mutations underlying these conditions are being identified at an increasing rate.
  • Clinical presentation can be complex, especially when multiple disorders affect a single breed.

Conclusions:

  • Hereditary ataxias represent a significant group of canine neurodegenerative diseases.
  • Genetic insights are crucial for advancing the clinical management of canine hereditary ataxias.
  • Suspicion of a breed-related neurodegenerative process is warranted in purebred dogs presenting with slowly progressive, symmetric ataxia.
