Genetic Sequencing Breakthrough to Aid Treatment for Congenital Hyperinsulinism, University of Exeter Medical School Study

Congenital hyperinsulinism is a genetic condition where a baby's pancreas secretes too much insulin. It affects approximately one in 50,000 live births and in severe cases requires the surgical removal of all or part of the pancreas. Researchers at the University of Exeter Medical School are the first in the world to utilise new genetic sequencing technology to sequence the entirety of a gene in order to identify mutations that cause hyperinsulinism. Previously, existing technology limited such sequencing to only part of the coding regions of the gene which meant that some mutations were missed.
