title: A novel germline mutation of the MEN1 gene, L259del, in a patient with sporadic multiple endocrine neoplasia type 1 (MEN1).
abstract: A Japanese woman was treated for insulinoma when she was 29 years old. Ten years later, heperparathyroidism and non-functioning adrenal tumor were found and she was diagnosed as having multiple endocrine neoplasia type 1 (MEN1). No other family members have developed MEN-related lesion(s). Genomic DNA of the patient was analyzed by sequencing for the MEN1 gene and a novel, three-base in-frame deletion resulting in deletion of an amino acid Leu259 was identified. Her two children showed a wild-type sequence at this codon.
