Summary
Systemic sclerosis (SSc) genetics involves multiple genes contributing to autoimmunity, fibrosis, and vasculopathy. Recent genome-wide studies identify new susceptibility loci and pathogenetic mechanisms for this complex disease.
Area of Science:
- Immunology
- Genetics
- Rheumatology
Background:
- Systemic sclerosis (SSc) is a complex autoimmune disease characterized by fibrosis, vasculopathy, and immune system activation.
- The genetic underpinnings of SSc involve multiple genes, with a known contribution from autoimmune-associated genes.
- Limited understanding exists regarding genetic factors specifically contributing to SSc-related vasculopathy and fibrosis.
Purpose of the Study:
- To comprehensively review recent genetic studies in Systemic Sclerosis (SSc).
- To highlight genes implicated in SSc autoimmunity, fibrosis, and vascular disease.
- To discuss findings from large-scale genetic association studies with replication strategies.
Main Methods:
- Review of recent literature on SSc genetics.
- Analysis of candidate gene approaches and genome-wide association studies (GWAS).
- Inclusion of studies with robust replication strategies.
Main Results:
- GWAS have identified novel genetic susceptibility loci for SSc.
- Specific genes associated with autoimmunity, fibrosis, and vascular disease in SSc have been identified.
- Replicated genetic findings strengthen the evidence for specific SSc susceptibility loci.
Conclusions:
- Genetic factors play a significant role in SSc pathogenesis, influencing autoimmunity, fibrosis, and vasculopathy.
- Genome-wide studies are crucial for uncovering new SSc-related genetic mechanisms.
- Further research into SSc genetics will advance understanding and potentially therapeutic strategies.

01:11Genome-wide Association Studies-GWAS
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

01:23Cystic 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...

01:43Incomplete 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.
01:22Myasthenia Gravis ll: Pathophysiology
The disease process of myasthenia gravis begins at the neuromuscular junction, where antibodies attack key proteins needed for muscle activation. This immune reaction weakens signal transmission, leading to the characteristic muscle fatigue and weakness that define the condition.Immune-Mediated DamageIn most individuals, antibodies target acetylcholine receptors (AChRs) on the postsynaptic membrane of muscle cells. By blocking acetylcholine binding, these antibodies prevent the nerve signal...
01:27Principles of Pharmacogenetics: Types of Genetic Variants
The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...
01:20The JAK-STAT Signaling Pathway
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...
