Neonatal diabetes

Gene: CISD2

Red List (low evidence)

Submitted on hehalf of Jayne Houghton (Royal Devon and Exeter Foundation Trust): "This gene is a known cause of Wolfram-like syndrome. There has been no reported cases of mutations in this gene in patients diagnosed with neonatal diabetes. However it is included in our Exeter panel since we have reported cases of neonatal diabetes in the other Wolfram gene, WFS1."

Comment on list classification: Kept rating as red, because this gene has not yet been shown to cause diabetes in the neonatal period [Elisa De-Franco (University of Exeter Medical School, personal communication, May 24th 2017].

Added CISD2 to the panel because it features on the Exeter 28-gene neonatal diabetes screen. However a correspondance from Dr. Elisa De-Franco (University of Exeter Medical School) reports that to date, all patients reported with homozygous CISD2 mutations developed diabetes outside the neonatal period, so for now this gene has not been shown to cause neonatal diabetes [personal communication, May 24th 2017].
