Multiple Sclerosis l: Introduction

Multiple Sclerosis l: Introduction

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...

Pleiotropy

Pleiotropy

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,...

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...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Bone Disorders

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...

Summary

This summary is machine-generated.

Hereditary multiple exostosis (HME) can cause spinal cord compression from cervical exostoses, leading to neurological deficits. Early diagnosis of HME is crucial for preventing such rare but serious complications.

Area of Science:

Orthopedics
Neurology
Genetics

Background:

Hereditary multiple exostosis (HME), also known as multiple osteochondromatosis, is an autosomal dominant disorder.
Characterized by osteocartilaginous exostoses, typically near the growth plates of long bones.
Potential complications include sarcoma transformation (1-5%) and neurological compression (1-9%).

Observation:

A 64-year-old man presented with long-term, progressive gait difficulties initially attributed to congenital rickets.
Diagnosis of HME was delayed until late in the disease progression.
Investigations revealed cervical myelopathy caused by vertebral exostosis and exostoses in other locations.

Findings:

Cervical myelopathy due to vertebral exostosis was identified as the cause of the patient's neurological symptoms.
Surgical decompression did not lead to improvement in the patient's gait.
This case highlights a rare neurological complication of HME.

Implications:

Emphasizes the importance of recognizing HME and its potential complications, including spinal cord compression.
Suggests that earlier diagnosis and intervention might prevent severe neurological deficits.
Underscores the need for increased awareness among clinicians regarding the diverse manifestations of HME.
