Abstract:
Recognition of deleterious non-synonymous single nucleotide polymorphism (SNPs) aids in the assessment of genetic basis of diseases and prediction of clinical phenotypes. In this study, data obtained from whole exome sequencing of Vechur cow using Illumina HiSeq 2500 platform is compared with that of crossbred cattle of Kerala. Sequence analysis of selected 18 mastitis resistant genes, evaluated the consequence of non-synonymous SNPs in these genes from both Vechur and crossbred cattle of Kerala, using sequence and structure-based computational tools such as SIFT, PROVEAN and I-MUTANT 2.0. Compared to Vechur cattle, incidence of missense deleterious mutation to effect protein functioning were relatively higher in crossbred cattle. These results on the type of genetic variants and its impact on normal functioning of a protein will assist to predict and enhance the disease resistance in cattle breeds.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
What is Gene Expression?
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...
