Genome-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.
GWAS does not require the identification of the target gene involved in...
Gene Families01:57

Gene Families

Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...

Translation

Lesson: Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.

Summary
This summary is machine-generated.

Hemoglobinopathies, including structural hemoglobin variants and thalassemias, are inherited disorders common in malarious regions. Identifying the specific molecular defect requires understanding the patient's ethnic background due to unique regional mutations.

Area of Science:

  • Genetics
  • Hematology
  • Molecular Biology

Background:

  • Hemoglobinopathies encompass inherited recessive disorders like structural hemoglobin variants and thalassemias.
  • These conditions exhibit high carrier frequencies in malaria-endemic areas globally.
  • Regional specificity means distinct populations possess unique combinations of hemoglobin and thalassemia mutations.

Purpose of the Study:

  • To highlight the importance of ethnic origin in diagnosing hemoglobinopathies.
  • To emphasize the need for understanding population-specific genetic variations in globin genes.

Main Methods:

  • This study is a review of existing knowledge on hemoglobinopathies.
  • It analyzes the geographical distribution and ethnic specificity of genetic mutations.

Main Results:

  • Hemoglobinopathies are diverse and regionally specific genetic disorders.
  • Carrier frequencies are notably high in populations from malarious regions.
  • Each ethnic group presents a unique spectrum of structural hemoglobin variants and thalassemia mutations.

Conclusions:

  • Ethnic origin is crucial for efficiently identifying the molecular basis of hemoglobinopathies.
  • Understanding population genetics aids in diagnosing and managing these inherited blood disorders.
