Repository, documented proof of the diagnosis must be provided on 

 a submission sheet which is available from the Institute for 

 Medical Research, or may be photocopied by the submitter from 

 pages 18-22. Without this information the culture cannot 

 be coded into the information retrieval system or be of value to 

 users of the Repository; and to conserve effort and expense the 

 Repository staff are instructed not to process a specimen unless 

 documentation of diagnosis is provided with the specimen. Sub- 

 mitters are therefore requested to fill in all applicable blanks 

 on the submission sheets. Please provide a family genealogy if 

 appropriate . 



No biopsies or cell cultures submitted to the Human Mutant 

 Cell Repository are to be obtained from a live fetus, defined 

 by the presence of pulse, circulation and other vital signs.
