Maturity-onset diabetes of the young panel (MODY)
Maturity-onset diabetes of the young panel (MODY) [27 genes]: It includes all genes associated with MODY (AKT2, BLK, CEL, GCK, HNF1A, HNF1B, HNF4A, INS, KCNJ11, KLF11, NEUROD1, PAX4, PDX1, PTF1A, RFX6, APPL1) and other early-onset forms of diabetes (EIF2AK3, FOXP3, GATA6, GLIS3, IER3IP1, INSIG2, INSR, NEUROG3, SLC2A2, TBC1D4 WFS1).
Adequate coverage for structural variants or CNVs (copy number variants).

Patients with early-onset diabetes (age generally <35 years) presenting with:
- Atypical characteristics for type 1 diabetes mellitus including absence of pancreatic islet autoantibodies, evidence for endogen insulin production beyond the “honeymoon period”, measurable C-peptide in the presence of hyperglycemia, low insulin treatment requirements, absence of ketoacidosis in the absence of insulin treatment.
- Atypical characteristics for diabetes mellitus type 2 including the following: onset of diabetes before age 45, absence of significant obesity, absence of acanthosis nigricans, normal triglyceride levels, and/or normal or elevated HDL-C.
- Mild, stable fasting hyperglycemia not progressing or not noticeably responding to pharmacological therapy.
- Extreme sensitivity to sulfonylureas.
- Extrapancreatic features (renal, hepatic, gastrointestinal).
- Personal or family history of neonatal diabetes or neonatal hypoglycemia.
- Family history of diabetes consistent with a dominant autosomal inheritance pattern, contrasting with diabetes types 1 and 2.
