| Abstract | Waardenburg syndrome (WS) is a hereditary auditory-pigmentary syndrome with hearing impairment and pigmentation anomaly of the skin and iris. In addition to these major symptoms, WS type 4 is associated with Hirschsprung disease. To date, three genes responsible for WS4 have been cloned: genes for a transcription factor SOX10, endothelin 3 (EDN3), and endothelin B receptor (EDNRB). We here describe a novel mutant mouse with a mutation of the Ednrb gene, and propose the mouse as an animal model of WS4. These mutants are with mixed genetic background of BALB/c and MSM (an inbred strain of Japanese wild mice) and have extensive white spotting. They died between 2 and 7 weeks after birth owing to megacolon: their colon distal to the megacolon lacked Auerbach’s plexus cells. Interestingly, these mutants did not respond to sound, and the stria vascularis of their cochlea lacked intermediate cells, i.e., neural crest-derived melanocytes. Since these symptoms resembled those of human WS4 and were transmitted in autosomal recessive hereditary manner, the mutants were named WS4 mice. Breeding analysis revealed that WS4 mice are allelic with piebald-lethal and JF1 mice, which are also mutated in the Ednrb gene. Mutation analysis revealed that their Ednrb lacked 318 nucleotides encoding Ednrb transmembrane domains owing to deletion of exons 2 and 3. Interaction between endothelin 3 and its receptor is required for normal differentiation and development of melanocytes and Auerbach’s plexus cells. We concluded that a missing interaction here led to a lack of these cells, which caused pigmentation anomaly, deafness, and megacolon in WS4 mice. |

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.
