Multiple endocrine neoplasia type 1 (MEN1) is a rare genetic disorder that is inherited in an autosomal dominant manner. The characteristics of the disease are the combined occurrence of tumors in glands of the endocrine system, such as the parathyroid glands, pituitary gland and endocrine pancreas. Germline mutations in the MEN1 gene are associated with the occurrence of MEN1 and genetic testing for this gene is generally used as a basis for diagnosis. In this paper, a case of MEN1 in a middle‑aged Japanese woman is reported. Direct sequencing analysis of the patient's DNA was performed and it revealed a MEN1 gene heterozygous germline (NM_130799.2:c.930delG) mutation in exon 5. This deletion/frameshift mutation produced a stop codon in the downstream sequence (NP_570711.1:p.Glu273LysfsTer7). To the best of our knowledge, this is the first report describing the NM_130799.2:c.930delG mutation as the basis for MEN1.
