Green List (high evidence)

Experts in EB have been including this gene as the 19th EB gene since December 2016 following publications in Nat Genet and AJHG. Now there are 26 individuals from 21 families reported. All mutations affect p.Met1 leading to generation of truncated more stable protein which affects ubiquinitination of keratin 14, compromising keratin filament integrity and leading to fragility of basal keratinocytes in the epidermis. This gene will definitely be included in the next international consensus for the classification of EB. I would be very appropriate to add this to the Genomics England panel for epidermolysis bullosa right now.
