Novel gene mutation in maturity-onset diabetes of the young: A case report

BACKGROUND: Maturity-onset diabetes of the young (MODY) is the most common monogenic type of diabetes. Recently, 14 gene mutations have been found to be associated with MODY. In addition, the KLF11 gene mutation is the pathogenic gene of MODY7. To date, the clinical and functional characteristics of...

Sumario:BACKGROUND: Maturity-onset diabetes of the young (MODY) is the most common monogenic type of diabetes. Recently, 14 gene mutations have been found to be associated with MODY. In addition, the KLF11 gene mutation is the pathogenic gene of MODY7. To date, the clinical and functional characteristics of the novel KLF11 mutation c. G31A have not yet been reported. CASE SUMMARY: We report of a 30-year-old male patient with a one-year history of nonketosis-prone diabetes and a 3-generation family history of diabetes. The patient was found to carry a KLF11 gene mutation. Therefore, the clinical data of family members were collected and investigated. A total of four members of the family were found to have heterozygous mutations in the KLF11 gene c. G31A, which resulted in a change in the corresponding amino acid p.D11N. Three patients had diabetes mellitus, and one patient had impaired glucose tolerance. CONCLUSION: The heterozygous mutation of the KLF11 gene c.G31A (p. D11N) is a new mutation site of MODY7. Subsequently, the main treatment included dietary interventions and oral drugs.
