Identification and In-silico Annotation of Functional Single Nucleotide Polymorphisms (SNPs) of the Candidate Gene Association with the Canine Transmissible Venereal Tumor Disease
Abstract: <div>Canine transmissible venereal tumor (CTVT) is a histiocytic tumor of the dog that mainly affects the external genitalia, commonly found at tropical and subtropical zones. In the present investigation, we undertook this work mainly to perform a computational analysis of snSNP in the BTNL2 to identify the possible mutations and proposed the model structure of the mutant protein. Four deleterious mutations were identified in BTNL2 in 109 and 319 residual positions. Moreover, we constructed the homolgus structure of native and mutant proteins to predicate the stability. I-Mutant was used for routine analysis of protein stability and for the single site mutation analysis. It was found that mutation of L to S at residual position 109 and A to T at 319 residue position has shown maximum negative effect on the protein stability and considered for further analysis. The mutational effect on the protein function was analyzed by project HOPE. It was found that the wild-type residue is very conserved, but a few other residue types have been</div><div>observed at this position too. Based on conservation scores this mutation is probably damaging to the protein. The present investigation was further used for molecular expect of the CTVT infection which might be useful in diagnosis and prevention of CTVT in canine.</div>
