Genome sequencing and analysis of public epigenomic data enabled the identification of disease-causing variants in a non-coding regulatory region of hexokinase 1 (HK1) in individuals with congenital hyperinsulinism. These variants caused inappropriate HK1 expression within pancreatic β-cells, which led to increased insulin secretion and hypoglycemia.

This study maps the key pancreatic islet transcription factors; we used this data to determine that HK1 variants reside in an islet regulatory region bound by transcription factors that are expressed in β-cells.

This study reports single-cell chromatin accessibility data in pancreatic islets; we used these data to determine accessibility of the HK1 regulatory region across islet cell types.
