| Abstract | DNA at the end point of the gene deletion associated with one form of hereditary persistence of fetal hemoglobin (HPFH) was cloned and used as a probe in gene mapping experiments to analyze the extent and approximate 3' end points of various deletions associated with HPFH and delta beta-thalassemia. The deletions in the two known forms of deletion-type HPFH were shown to be considerably more extensive than in the two cases of delta beta-thalassemia studied. The overall extents of the deletions in the two types of HPFH were quite similar in both cases and the 3' end points were located at a minimum distance of approximately equal to 52 and 57 kilobases from the 3' extremity of the beta-globin gene. In contrast, the 3' end points of the deletions in the two forms of delta beta-thalassemia were located approximately equal to 5 and 10 kilobases to the 3' side of the beta-globin gene. The extent of these deletions and the nature of the DNA brought into the vicinity of the gamma-globin genes by the deletions may therefore be a more important influence on the phenotype of the deletions than the specific nature of the DNA sequences that are deleted within the non-alpha-globin gene cluster as a result of the mutations. |

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.
