Sarah Leigh (Genomics England Curator)

Comment on list classification: This gene is being demoted to red as pathogenicity is caused by changes to methylation of this gene

Ellen McDonagh (Genomics England Curator)

"Some microduplications encompassing IGF2 have been reported in association with Beckwith-Wiedemann syndrome" - Comment made by Richard Scott (North Thames GMC/UCL), Oct. 9, 2015, 9:47 p.m.
Created: 29 Mar 2016, 1:32 p.m.
Mutational spectrum tested for by the UKGTN: loss of methylation at LIT1 (KvDMR1 within LIT1 - KCNQ1OT1 is the HGNC-approved symbol for LIT1), Hypermethylation of H19, duplication of paternally inherited 11p15 region, paternal uniparental disomy of 11p15 region, maternal H19 DMR microdeletion, maternal KvDMR1 microdeletion. ICR1 is the H19/IGF2-imprinting control region located in the 11p15.5 region.
