Summary
Glycogene mutations cause over 40 congenital diseases, with many more likely undiscovered. Understanding glycogene function is crucial for diagnosing and treating these complex genetic disorders.
Area of Science:
- Genetics
- Biochemistry
- Molecular Biology
Background:
- Glycogenes, essential for glycan assembly, constitute 1-2% of the human genome.
- Over 40 congenital diseases linked to glycogene mutations are known, with many more suspected.
- Mutations in glycogenes affecting multiple glycan classes cause complex phenotypes and diagnostic challenges.
Purpose of the Study:
- To highlight the significance of glycogene mutations in congenital diseases.
- To emphasize the need for understanding glycogene function for diagnosis and treatment.
- To address the challenges in identifying glycogene targets and developing new diagnostic and therapeutic approaches.
Main Methods:
- Biochemical methods have been instrumental in discovering disease-causing glycogenes.
- Emerging techniques like homozygosity mapping are increasingly necessary.
- Identifying glycogene target proteins and their roles in disease remains a significant challenge.
Main Results:
- Glycogene mutations are implicated in a growing number of congenital diseases.
- Complex phenotypes arise from mutations in glycogenes with broad glycan synthesis roles.
- Current diagnostic and therapeutic strategies for glycogene-related disorders are limited.
Conclusions:
- Further research is needed to discover all causative glycogene mutations for congenital diseases.
- Developing novel diagnostic procedures is essential for accurate patient diagnosis.
- Effective treatments and animal models are critically lacking for these disorders.

01:25Protein Glycosylation
Glycosylation, the most common post-translational modification for proteins, serves diverse functions. Adding sugars to proteins makes the proteins more resistant to proteolytic digestion. Glycosylated proteins can act as markers and receptors to promote cell-cell adhesion. Additionally, they have many essential quality control functions in the cell, such as correct protein folding and facilitating transport of misfolded proteins to the cytosol, which can be degraded.

01:05Proteoglycans
Glycans, a class of complex heterogeneous molecules, can be covalently attached to proteins to form glycosylated proteins that regulate various physiological and pathological processes. Glycosylated proteins or glycoproteins comprise N-linked and O-linked oligosaccharides. O-glycosylation is the most common type of protein glycosylation. Here, glycans attach to the oxygen atom of the hydroxyl groups of Serine or Threonine residues. O-linked glycosylation occurs later in protein processing,...
01:24Oligosaccharide Assembly
Protein glycosylation starts in the ER lumen and continues in the Golgi apparatus. Glycosyltransferases catalyze the addition of sugar molecules or glycosylation of proteins. Usually, these enzymes add sugars to the hydroxyl groups of selected serine or threonine residues to form O-linked glycans or the amino groups of asparagine residues to form N-linked glycans. Different positions on the same polypeptide chain can contain differently linked glycans.

01:26Type I Diabetes II: Pathophysiology
Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...
01:27Glucose Transporters
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

01:22Diabetes Mellitus: Overview and Type I Subtype
Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
