Congenital microcephaly.
Summary
Genetic congenital microcephaly involves complex genetic causes affecting cell division, DNA repair, and cell cycle checkpoints. Understanding these interconnected cellular pathways is key to identifying new therapeutic targets.
Area of Science:
- Genetics
- Cell Biology
- Developmental Biology
Background:
- Genetic congenital microcephaly has complex and multifactorial etiologies.
- Recent advances have identified numerous genetic causes and revealed common pathomechanisms.
Purpose of the Study:
- To overview key pathomechanistic themes in profound congenital microcephaly.
- To emphasize the interconnected nature of these cellular processes.
Main Methods:
- Literature review of genetic causes and cellular pathomechanisms.
- Analysis of common themes in molecular and cellular defects.
Main Results:
- Identified themes include abnormal mitotic spindle structure, centrosome abnormalities, altered cilia function, impaired DNA repair and replication, and cell cycle checkpoint defects.
- These cellular processes are highly interconnected.
- Defects in single genes can impact multiple pathways.
Conclusions:
- Profound congenital microcephaly arises from complex, interconnected cellular pathway disruptions.
- Understanding these shared mechanisms is crucial for future research and therapeutic development.

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

01:30Neurulation
40.2K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this...

Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
