A monogenic form of diabetes often misdiagnosed as type 1 or type 2. At least 13 MODY genes have been identified.
How Genetic Is MODY (Maturity-Onset Diabetes of the Young)?
MODY (Maturity-Onset Diabetes of the Young) has a strong genetic basis. Research estimates heritability at approximately 100%, meaning genetic factors account for the majority of variation in whether individuals develop this condition.
Key genes associated with MODY (Maturity-Onset Diabetes of the Young): HNF1A GCK HNF4A. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.

Does Family History Matter for MODY (Maturity-Onset Diabetes of the Young)?
Yes — family history is one of the strongest predictors of MODY (Maturity-Onset Diabetes of the Young). If a first-degree relative (parent, sibling, or child) has been diagnosed, your own risk may be significantly elevated. Discussing your family history with a healthcare provider or genetic counsellor is strongly recommended.
