Silent point mutation polymorphism of the bovine CD18 encoding gene

Area of Science:

• Animal Genetics
• Molecular Biology
• Biotechnology

Background:

• The ITGB2 gene encodes the CD18 subunit, crucial for cell adhesion.
• Silent point mutations can influence gene function and serve as genetic markers.
• Understanding genetic variations in cattle is vital for breeding programs.

Purpose of the Study:

• To develop a PCR-RFLP method for identifying a specific silent point mutation in the bovine ITGB2 CD18 subunit gene.
• To screen a Polish Black-and-White cattle population for this mutation.
• To investigate the potential of this mutation as a molecular marker for milk productivity.

Main Methods:

• Polymerase Chain Reaction - Restriction Fragment Length Polymorphism (PCR-RFLP) technique.
• Genotyping and allele frequency analysis in a population of 210 Polish Black-and-White cattle.
• Data analysis of genotype and allele frequencies in sires and cows.

Main Results:

• A PCR-RFLP procedure was successfully established for detecting the silent point mutation in the ITGB2 CD18 gene.
• Genotype and allele frequencies of the mutation were determined in the studied cattle population.
• The study identified the presence and distribution of this specific genetic polymorphism.

Conclusions:

• The developed PCR-RFLP method is effective for recognizing the silent point mutation in the bovine ITGB2 CD18 gene.
• Further research is required to validate the association between this CD18 silent mutation and high milk productivity.
• This genetic marker holds potential for future applications in cattle breeding for enhanced milk yield.
