Summary
Polyneuropathy in Alaskan Malamutes is a hereditary disease. Genetic factors influence its expression, leading to varied symptoms from severe to subclinical forms.
Area of Science:
- Veterinary Genetics
- Canine Neurology
Background:
- Polyneuropathy is a debilitating condition affecting nerve function.
- Understanding the genetic basis of canine diseases is crucial for effective management.
Purpose of the Study:
- To investigate the genetic underpinnings of polyneuropathy in Alaskan Malamutes.
- To determine the mode of inheritance for this neurological disorder.
Main Methods:
- Pedigree analysis of 131 Alaskan Malamutes.
- Neurological examinations, electrodiagnostics, and nerve/muscle biopsies in 10 dogs.
- Segregation analysis using four genetic models on 71 dogs.
Main Results:
- Confirmed polyneuropathy with axonal degeneration and hypomyelination in affected dogs.
- Identified subclinical neuromuscular changes in clinically normal relatives.
- A polygenic inheritance model best explained the observed disease patterns.
Conclusions:
- Polyneuropathy in Alaskan Malamutes is a hereditary condition.
- Variable phenotypic expression, including subclinical forms, is characteristic.
- Genetic factors must be considered in future research and breeding programs.

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...

02:59Animal Mitochondrial Genetics
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...
01:43Incomplete Dominance
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.

Overview
01:33Pleiotropy
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,...

DefinitionDiabetic neuropathy is nerve damage caused by long-standing diabetes mellitus. It results directly from prolonged high blood sugar levels.PathophysiologyThe pathophysiology of diabetic neuropathy involves both metabolic and vascular disturbances triggered by chronic hyperglycemia.Metabolic injury: Elevated glucose levels activate the polyol pathway within nerve cells, leading to the accumulation of sorbitol and fructose. This increases oxidative stress, disrupts normal nerve...
