Genetic analysis of the polymorphism of the human apolipoprotein E using automated solid-phase sequencing

Area of Science:

• Genetics
• Molecular Biology
• Biochemistry

Background:

• The human apolipoprotein E (APOE) gene is a key determinant of serum cholesterol levels.
• Polymorphisms in the APOE gene are associated with various health conditions, including cardiovascular diseases.
• Accurate and efficient genotyping of APOE alleles is important for clinical diagnosis and research.

Purpose of the Study:

• To develop and validate a direct sequencing method for analyzing APOE gene polymorphism.
• To establish a semi-automatic procedure adaptable for clinical diagnosis.

Main Methods:

• Direct sequencing of amplified DNA using a polymerase chain reaction (PCR).
• Solid-phase DNA immobilization on magnetic beads.
• Semi-automatic sequencing procedure without the need for cloning steps.

Main Results:

• The developed method successfully analyzed the polymorphism in the human apolipoprotein E gene.
• The solid-phase sequencing approach accurately resolved nucleotide sequences in both homozygous and heterozygous samples.
• The method demonstrated efficiency and adaptability for clinical diagnostic applications.

Conclusions:

• A novel, direct, solid-phase sequencing method for APOE gene polymorphism analysis has been established.
• This technique offers a robust and efficient alternative to traditional methods, suitable for clinical settings.
• The method facilitates accurate genotyping of APOE alleles, aiding in the assessment of cholesterol metabolism and related health risks.
