INS and diabetes mellitus: Maturity-onset diabetes of the young (MODY) represents a group of monogenic diabetes caused by autosomal dominant inherited defects in gene related to insulin secretion and estimated to account for 1 to 5% of the diabetes population.1MODY appears to primarily affect the Caucasian population, with an onset of diabetes typically occurring before the age of 30 years.1The scarcity of prevalence data for MODY in non-Caucasian ethnicities is conspicuous, likely stemming from an insufficient depth of research and genetic investigations in these ethnic groups.
