Genetic Leukoencephalopathies in Adults.
Continuum (Minneapolis, Minn.)
|June 5, 2016
Summary
Genetic white matter disorders are increasingly diagnosed in adults due to advances in genetic testing. Recognizing these hereditary leukoencephalopathies is crucial for prognosis and family counseling.
Area of Science:
- Neurology
- Genetics
- Neuroimaging
Background:
- Over 100 heritable disorders can cause abnormal white matter on neuroimaging.
- Acquired disorders are more common causes of leukoencephalopathy in adults than genetic ones.
- Clinicians must identify features suggesting a genetic etiology for white matter abnormalities.
Observation:
- Next-generation sequencing has transformed the diagnosis of adult white matter disorders.
- Molecular causes for several adult-onset hereditary white matter diseases have been identified recently.
Findings:
- Identifying a genetic cause for white matter disease impacts prognosis and family counseling.
- Awareness of common hereditary white matter disorders aids in distinguishing them from acquired conditions.
- A systematic diagnostic approach is essential for hereditary leukoencephalopathies.
Implications:
- Genetic testing advances aid in diagnosing adult-onset white matter disorders.
- Accurate diagnosis of hereditary leukoencephalopathies is vital for patient management.
- Understanding genetic etiologies improves genetic counseling for affected families.

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...

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.

1
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

10.0K
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...
