| 520 | _aGene expression is tightly regulated with many genes exhibiting cell-specific silencing when their protein product would disrupt normal cellular function(1). This silencing is largely controlled by non-coding elements and their disruption might cause human disease(2). We performed gene-agnostic screening of the non-coding regions to discover new molecular causes of congenital hyperinsulinism. This identified 14 non-coding de novo variants affecting a 42bp conserved region encompassed by a regulatory element in intron 2 of Hexokinase 1 (HK1). HK1 is widely expressed across all tissues except for liver and pancreatic beta-cells and is thus termed a "disallowed gene" in these specific tissues. We demonstrated that the variants result in a loss of repression of HK1 in pancreatic beta-cells, thereby causing insulin secretion and congenital hyperinsulinism. Using epigenomic data accessed from public repositories, we demonstrated that these variants reside within a regulatory region that we determine to be critical for cell-specific silencing. Importantly, this has revealed a disease mechanism for non-coding variants that cause inappropriate expression of a disallowed gene. | ||
