| Abstract | Polymorphisms in the coding region of the prion protein gene (PRNP) have been associated with the susceptibility and incubation period of prion diseases in humans and sheep. However, polymorphisms in this part of the bovine PRNP gene do not affect the classical bovine spongiform encephalopathy (BSE) susceptibility in cattle. Studies carried out in Germany have shown that insertion/deletion-type polymorphisms located in the promoter region of the bovine prion gene are possible genetic factors modulating BSE susceptibility by changing the level of PRNP expression. No such association was observed for atypical BSE cases; however, due to the rare nature of the disease, these results should be confirmed. Additionally, a single nonsynonymous mutation in PRNP codon 211 (E211K) was described in one H-type BSE case in the USA; however, it was not found in any other cases. Here, we performed genetic characterization of PRNP promoter indel variations and determined the polymorphism of open reading frames (ORFs) of PRNP and bovine prion-like Shadoo (SPRN) genes in six Polish atypical BSE cases and compared these results to the population of clinically healthy Polish Holstein cattle. No potentially pathogenic mutations were found in the PRNP ORF in atypical BSE-affected cattle, but our study showed a high frequency of deletions at the indel loci of PRNP promoter in these animals. Additionally, a rare sequence variation in the SPRN protein-coding sequence was found in one L-type atypical BSE-affected animal. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
