The British 1958 birth cohort1 is based on all persons born in Britain during one week in March in 1958. Participants have been followed throughout their lives and biomedical information has been collected at various time points. Biological samples were collected from the cohort during medical examinations between Sept 2002 and March 2004. Funding for creation of a blood derived DNA bank was provided by the MRC (strategic project grant G0000934). Funding for creation of lymphoblastoid cell lines, cell line derived DNA extraction, banking and distribution was funded by the Wellcome Trust (grant no 068545).

DNA and cell line banks were created in the ALSPAC Laboratory. Blood derived DNA is available from 8018 individuals and has been used successfully in several genotyping studies.

Cell lines from 2288 individuals were created at ECCAC, Porton and a further 5239 in the ALSPAC laboratory. DNA has been extracted from all of these samples and has been organised into geographically representative subgroups of samples specifically for use as control samples in case control studies. Samples have been distributed to over 20 collaborators and were used as control samples by the Wellcome Trust Case Control Consortium2.

Further funding was obtained in 2006 for management of the cell line and DNA banks and distribution of samples (grant details). This funding will end on 31st August 2007 and we are therefore applying for additional funds to continue these functions.
