In silico screening and identification of deleterious missense SNPs along with their effects on CD-209 gene: An insight to CD-209 related-diseases.

ABSTRACT: DC-SIGN receptor articulated by macrophages and dendritic cells is encoded by CD209 gene and plays a role to activate and proliferate the T-lymphocytes in response of virus attack. The dysfunctional activity of DC-SIGN receptor because of missense SNPs can lead to cause dengue haemorrhage fever, HIV-1 infection etc. Out of 11 transcripts of CD209, all missense SNPs of canonical transcript were retrieved from Ensembl database and evaluated by their deleteriousness by using Polyphen-2, PMut, SIFT, MutPred, PROVEAN and PhD-SNP together with stimulation of its complete 3D structure. 10 nsSNPs were chosen depending on both the significance value of nsSNP and their prediction among SNPs evaluating servers which are based on different algorithms. Moreover, the position and native role of 10 nsSNPs in wild 3D model has been described which assist to acknowledge their importance. This study urges the researcher's community to experimentally validate these SNPs and their association in causing the diseases like dengue fever, Tuberculosis etc.

Project description:Hennekam lymphangiectasia-lymphedema syndrome has been linked to single-nucleotide polymorphisms in the CCBE1 (collagen and calcium-binding EGF domains 1) gene. Several bioinformatics methods were used to find the most dangerous nsSNPs that could affect CCBE1 structure and function. Using state-of-the-art in silico tools, this study examined the most pathogenic nonsynonymous single-nucleotide polymorphisms (nsSNPs) that disrupt the CCBE1 protein and extracellular matrix remodeling and migration. Our results indicate that seven nsSNPs, rs115982879, rs149792489, rs374941368, rs121908254, rs149531418, rs121908251, and rs372499913, are deleterious in the CCBE1 gene, four (G330E, C102S, C174R, and G107D) of which are the highly deleterious, two of them (G330E and G107D) have never been seen reported in the context of Hennekam syndrome. Twelve missense SNPs, rs199902030, rs267605221, rs37517418, rs80008675, rs116596858, rs116675104, rs121908252, rs147974432, rs147681552, rs192224843, rs139059968, and rs148498685, are found to revert into stop codons. Structural homology-based methods and sequence homology-based tools revealed that 8.8% of the nsSNPs are pathogenic. SIFT, PolyPhen2, M-CAP, CADD, FATHMM-MKL, DANN, PANTHER, Mutation Taster, LRT, and SNAP2 had a significant score for identifying deleterious nsSNPs. The importance of rs374941368 and rs200149541 in the prediction of post-translation changes was highlighted because it impacts a possible phosphorylation site. Gene-gene interactions revealed CCBE1's association with other genes, showing its role in a number of pathways and coexpressions. The top 16 deleterious nsSNPs found in this research should be investigated further in the future while researching diseases caused CCBE1 gene specifically HS. The FT web server predicted amino acid residues involved in the ligand-binding site of the CCBE1 protein, and two of the substitutions (R167W and T153N) were found to be involved. These highly deleterious nsSNPs can be used as marker pathogenic variants in the mutational diagnosis of the HS syndrome, and this research also offers potential insights that will aid in the development of precision medicines. CCBE1 proteins from Hennekam syndrome patients should be tested in animal models for this purpose.
