Background:
Pleomorphic adenoma gene 1 (PLAG1) is a zinc finger transcription factor and is widely known to play an important role in regulating growth traits in bovine.
Aim:
This study aimed to evaluate the association of PLAG1 polymorphisms with body weight and measurement traits of Brahman cattle.
Methods:
A total of 57 blood samples of Brahman cattle and their body weight and measurement traits have been collected. Moreover, the polymerase chain reaction-restriction fragment length polymorphism method was used to determine the genotypes of the three polymorphisms in PLAG1, namely g.48308C>T, g.32212 (19 bp indel), and g.45233 T>C. A mix model effect was performed to evaluate the association of PLAG1 with body weight and measurement traits, while the Tukey HSD test was used to compare the means among genotypes.
Results:
Genotype variations were observed for the g.48308C>T single nucleotide polymorphism (SNP) and 19 bp indel. In detail, the CC and CT genotypes of g.48308C>T SNP were identified and all possible genotypes of 19 bp indel were also identified. On the other hand, g.45233T>C SNP showed no variation. The statistical analysis revealed that SNP g.48308C>T and 19 bp indel had a significant effect on body weight and chest girth (p < 0.05). Both CC genotypes of g.48308C>T SNP and DD genotype of 19 bp indel of the PLAG1 were favorable for those two traits.
Conclusion:
Based on these results, the SNP g.48308C>T and 19 bp indel in the PLAG1 could be a candidate marker for body weight and chest girth in the Brahman cattle population at the Center for Superior Animal Breeding and Forage (BPTU-HPT) Sembawa.

Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
