Whole‑exome sequencing in Russian children with non‑type 1 diabetes mellitus reveals a wide spectrum of genetic variants in MODY‑related and unrelated genes.

ABSTRACT: The present study reports on the frequency and the spectrum of genetic variants causative of monogenic diabetes in Russian children with non‑type 1 diabetes mellitus. The present study included 60 unrelated Russian children with non‑type 1 diabetes mellitus diagnosed before the age of 18 years. Genetic variants were screened using whole‑exome sequencing (WES) in a panel of 35 genes causative of maturity onset diabetes of the young (MODY) and transient or permanent neonatal diabetes. Verification of the WES results was performed using PCR‑direct sequencing. A total of 38 genetic variants were identified in 33 out of 60 patients (55%). The majority of patients (27/33, 81.8%) had variants in MODY‑related genes: GCK (n=19), HNF1A (n=2), PAX4 (n=1), ABCC8 (n=1), KCNJ11 (n=1), GCK+HNF1A (n=1), G
