Type 2 & other diabetes

The landscape of monogenic diabetes in Italy. Comparisons with other European countries

Diabetes Res Clin PractPublished Cohort study

Authors' conclusion

Monogenic diabetes in Italy only partially resembles that in other countries.

Study context

Population
White unrelated patients with suspected monogenic diabetes across wide age-range at diagnosis, Italy, 2017–2025
Participants
521 unrelated patients
Outcome
Pathogenic/likely-pathogenic variants (diagnostic yield)
Methodological detailsNGS and Sanger sequencing, variants classified per gene-specific expert-panel or ClinGen/ACMG guidelines
  • NGS and Sanger sequencing
  • Variants classified per gene-specific expert-panel or ClinGen/ACMG guidelines

Main finding

As reported in the abstract

Pathogenic/likely-pathogenic variants

Patients with pathogenic/likely-pathogenic variants

127 of 521

GCK-diabetes most common (in contrast to UK, France and Norway)
