Sex-linked Disorders

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.

Satellite Stem Cells and Muscular Dystrophy

Satellite Stem Cells and Muscular Dystrophy

Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...

Animal Mitochondrial Genetics

Animal 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...

Disorders of the Skeletal Muscle

Disorders of the Skeletal Muscle

The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Lethal Alleles

Lethal Alleles

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...

Genetics
Clinical Medicine

Background:

Hereditary myelopathies encompass diverse inherited neurological disorders affecting the spinal cord.
These conditions often involve extraspinal structures like peripheral nerves and the cerebellum, aiding diagnosis.
Spinal dysraphisms are excluded due to differing etiology and heritability.

Purpose of the Study:

To guide clinicians in the clinical recognition of hereditary myelopathies.
To assist in the differential diagnosis of these inherited spinal cord disorders.
To highlight the spectrum and clinical paradigms of hereditary myelopathies.

Main Methods:

Review of clinical features and diagnostic approaches for hereditary myelopathies.
Classification of hereditary myelopathies into four main clinical paradigms.
Illustration of clinical examples to emphasize diagnostic challenges.

Main Results:

Hereditary myelopathies involve the spinal cord (dorsal columns, dorsal root ganglia, corticospinal tracts, anterior horn cells) and extraspinal structures.
Four primary clinical paradigms are identified: spinocerebellar ataxia, motor neuron disorder, leukodystrophy, and predominantly CNS distal motor-sensory axonopathy.
Extraspinal manifestations are crucial for recognizing specific hereditary myelopathy syndromes.

Conclusions:

Classifying hereditary myelopathies facilitates clinical recognition and differential diagnosis.
Understanding the four clinical paradigms aids in diagnosing these complex inherited neurological conditions.
This review provides a framework for clinicians managing patients with suspected hereditary myelopathies.
