Summary
Systemic sclerosis (SSc) is a complex connective tissue disease. Research is exploring genetic and environmental factors, focusing on fibrosis, immune response, and vascular disease, to understand its mechanisms.
Area of Science:
- Immunology
- Genetics
- Pathology
Background:
- Systemic sclerosis (SSc) is a connective tissue disease with unknown pathogenesis.
- SSc involves fibrosis, vasculopathy, and immune system activation.
- Environmental and genetic factors are implicated in SSc development.
Purpose of the Study:
- To summarize recent advances in understanding SSc pathogenesis.
- To explore candidate genes related to fibrosis, immune response, and vascular disease in SSc.
Main Methods:
- Review of current research on SSc.
- Analysis of genetic and environmental factors.
- Screening of candidate genes in three key areas: fibrosis, immune response, and vascular disease.
Main Results:
- Low concordance in identical twins suggests complex inheritance.
- Higher concordance for SSc-associated autoantibodies and fibroblast gene expression.
- Candidate-gene approaches have not yet identified clear polymorphism associations.
Conclusions:
- Understanding SSc requires investigating fibrosis, immune response, and vascular disease pathways.
- Further research into genetic and environmental interactions is crucial.
- Identifying specific genetic markers remains a challenge.

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.

01:27Principles 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...
01:23Cystic 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...

01:29Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu
Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...
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.
01:33Pleiotropy
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...
