Summary
C3 glomerulopathy typically involves complement system mutations. This study identifies a rare heterozygous laminin β2 mutation in a patient with C3 glomerulonephritis, ocular, and central nervous system issues.
Area of Science:
- Nephrology
- Genetics
- Complement System Biology
Background:
- C3 glomerulopathy is a rare kidney disease characterized by complement system dysregulation.
- It is often associated with C3 nephritic factor or mutations in complement regulatory proteins like factor H, factor I, or C3.
Observation:
- This report details a case of C3 glomerulonephritis with unusual ocular and central nervous system manifestations.
- The patient presented with a heterozygous mutation in laminin β2, a component of glomerular basement membranes.
Findings:
- The identified heterozygous laminin β2 mutation is a novel finding in the context of C3 glomerulopathy.
- The specific role and significance of this laminin β2 mutation in the observed clinical presentation remain to be elucidated.
Implications:
- This case expands the known genetic landscape of C3 glomerulopathy.
- Further research is needed to understand the contribution of laminin β2 mutations to complement-mediated kidney diseases and associated systemic conditions.

00:55Laminins are the Adhesive Proteins of Basal Lamina
2.3K
Laminins are heterotrimeric proteins with high molecular mass found in the extracellular matrix. Each laminin molecule is composed of three chains, viz. alpha, beta, and gamma, coded by five, four, and three paralogous genes, respectively. Laminins are categories based on the compositions of the three chains.
In humans, the five forms of alpha chains are LAMA 1, LAMA 2, LAMA 3, LAMA 4, and LAMA 5. The four forms of beta chains are LAMB 1, LAMB 2, LAMB 3, and LAMB 4. The three forms of gamma...

2.4K
Type IV collagen is a 400 nm long, network-forming collagen that acts as a barrier between the epithelial and endothelial cells. Type IV collagen forms the backbone of the basement membrane by scaffolding with laminin, entactin, proteoglycans, and fibronectin. Apart from rendering structural support to the basement membrane, it also helps entail signaling potentials necessary for both pathological and physiological functions.

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

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...

01:03Basal Lamina are the Specialized Form of ECM
3.0K
The basal lamina is a thin extracellular layer that lies underneath the cells and separates them from other tissues. The three layers of the basal lamina are lamina lucida, lamina densa and lamina reticularis. The basal lamina, a mixture of glycoproteins and collagen, provides an attachment site for the epithelium, separating it from underlying connective tissue. The framework of basal lamina has other essential proteins such as laminins mesh, perlecan, entactin, and type IV collagen.

25.9K
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.
