Insights

Charcot-Marie-Tooth disease (CMT) is a common inherited neurological disorder. Advanced genetic technologies are improving diagnosis and discovering new genes for CMT, aiding understanding of its mechanisms.

Area of Science:

  • Genetics
  • Neurology
  • Molecular Biology

Background:

  • Charcot-Marie-Tooth disease (CMT) is a prevalent inherited peripheral nervous system disorder causing muscle weakness and atrophy.
  • Over 30 genes are linked to CMT, significantly advancing diagnostics and understanding of disease mechanisms.
  • Despite advances, molecular diagnosis remains elusive in 30-50% of CMT patients, indicating undiscovered genetic factors.

Purpose of the Study:

  • To review genetic and functional data for various CMT forms.
  • To highlight recent advancements in gene discovery for CMT using high-throughput genetic technologies.
  • To discuss the impact of these technologies on CMT diagnosis and research.

Main Methods:

  • Review of genetic and functional data from CMT research.
  • Analysis of data from systematic genetic screening in large CMT patient cohorts.
  • Focus on findings from SNP chips, sequence capture, and next-generation DNA sequencing in CMT families.

Main Results:

  • Current genetic screening identifies causative mutations in only 50-70% of CMT cases.
  • Highly parallel genetic technologies are instrumental in identifying novel CMT-associated genes.
  • These technologies are enhancing the diagnostic yield and understanding of CMT pathophysiology.

Conclusions:

  • Additional genes beyond the known 30+ are implicated in Charcot-Marie-Tooth disease.
  • Next-generation sequencing and related technologies are crucial for future CMT gene discovery.
  • These advancements will significantly improve molecular diagnostics and therapeutic strategies for CMT.

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.
Animal Mitochondrial Genetics02:59

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...

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...
Genetic Screens02:46

Genetic Screens

Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which result in visible changes...
Genomics02:02

Genomics

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...
