Abstract: We have determined the non-synonymous Single-Nucleotide Polymorphisms (nsSNPs) of PLD2 gene and its variations in different populations to understand its role in hypertension. Out of 350 SNPs, six are found to be non-synonymous, of which two showed significant damaging effect and SNP variability with large differences among the Minor Allele Frequency (MAF) observed in various populations. The amino acid change found for rs2286672 is from arginine to cysteine, i.e., from largest amino acid containing guanidino group to a small amino acid containing sulfhydryl group, and for rs3764897, it is from glycine to serine, i.e., from a hydrophobic amino acid to a hydrophilic amino acid. Hence, owing to the complete change in side chains and polarity of the amino acid residues brought about by these SNPs, the structure of the protein might be altered and hence the function might be affected, leading to dysregulation of blood pressure.
