Insights

Genetic defects cause many early-onset childhood movement disorders like ataxia and parkinsonism. This review highlights genetically defined conditions with available clinical testing.

Area of Science:

  • Pediatric Neurology
  • Genetics
  • Movement Disorders

Background:

  • Childhood movement disorders frequently stem from genetic causes.
  • Recent advances in genetic information have identified numerous genetic defects linked to various movement disorders.
  • These include ataxia, parkinsonism, dystonia, tremor, and spastic paraparesis.

Purpose of the Study:

  • To review genetically defined, early-onset movement disorders in children.
  • To emphasize conditions with available clinical or research testing.

Main Methods:

  • Literature review focusing on genetic causes of early-onset movement disorders.
  • Identification of disorders with available diagnostic or research testing.

Main Results:

  • Numerous genetic defects underlying early-onset movement disorders have been identified.
  • Specific genetic conditions associated with ataxia, parkinsonism, dystonia, tremor, and spastic paraparesis are discussed.
  • Emphasis on disorders with available genetic testing.

Conclusions:

  • Genetic factors play a significant role in early-onset pediatric movement disorders.
  • Understanding these genetic underpinnings is crucial for diagnosis and management.
  • Availability of genetic testing aids in the clinical evaluation of these conditions.

Human Genetics01:28

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...
Parkinson Disease l: Introduction01:24

Parkinson Disease l: Introduction

Parkinson’s disease is a chronic, progressive neurodegenerative disorder that primarily affects movement. It is characterized by motor symptoms such as resting tremors, muscle rigidity, bradykinesia (slowness of movement), and postural instability. Patients may notice hand tremors at rest, stiffness during movement, or a shuffling gait. In addition to motor features, non-motor symptoms include sleep disturbances, mood and behavioral changes, constipation, and cognitive impairment, all of which...
Genetic Lingo02:25

Genetic Lingo

An organism is diploid if it inherits two variants, or alleles, of each gene, one from each parent. These two alleles constitute the genotype for a given gene. The term genotype is also used to refer to an organism’s complete set of genes. A diploid organism with two identical alleles has a homozygous genotype, whereas two different alleles indicate a heterozygous genotype. Observable traits arising from genotypes are called phenotypes, which can also be influenced by environmental factors. An...
Sex-linked Disorders02:28

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.Y chromosome mutations are called “Y-linked” and only affect males since they alone carry a copy of that chromosome. Mutations to the relatively small Y chromosome can impact male sexual function and secondary sex characteristics. Y-chromosome infertility is a disorder that affects sperm...
Behavioral Genetics and Its Designs01:23

Behavioral Genetics and Its Designs

Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.
The primary methodologies used in behavior genetics include family studies, twin studies, and adoption studies, each providing unique...
Incomplete Dominance01:43

Incomplete 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.
