Genotyping of friesian horses to detect a hydrocephalus-associated c.1423C>T mutation in B3GALNT2 using PCR-RFLP and PCR-PIRA methods: Frequency in stallion horses in México.

This study is about genotyping Friesian horses to detect a mutation related to hydrocephalus, a genetic disease, using two specific scanning methods. The researchers also determined the frequency of this mutation among Friesian stallion horses in Mexico.

Objective of the Research

The research paper describes a study that aimed to genetically type or “genotype” Friesian stallion horses in Mexico for the presence of a c.1423C > T mutation in the B3GALNT2 gene, which is associated with the recessive hereditary disease, hydrocephalus.

• Hydrocephalus is a disease that can cause abortion, stillbirth, or necessitate the euthanization of a newborn foal.

Methodology

The researchers employed two techniques to detect the presence of the mutation.

• PCR-RFLP (Polymerase Chain Reaction – Restriction Fragment Length Polymorphism) is a molecular biology technique used to detect specific mutations within a gene.
• PCR-PIRA (Polymerase Chain Reaction – Primer-Introduced Restriction Analysis) is another technique that offers easier detection of the mutated genes with the help of mutation-specific primers.

Using these methods, the researchers undertook a preliminary genotyping survey on 83 Friesian stallion horses randomly selected.

Findings

The results of the study showed that the mutation is present within the tested population.

• The studies revealed that the frequency of the mutant T allele, or the variant form of a gene, was approximately 9.6% among the tested population.

These findings are significant as they provide valuable information about the presence and frequency of hydrocephalus-associated genetic mutation among Friesian horses in Mexico.
