Tran Lea Chantal , Ballandone Celine , Vaiman Daniel , Barbaux Sandrine , Richard Nicolas , Kottler Marie-Laure

Background: GNAS gene is a complex imprinted locus, resulting in the expression of at least four transcripts (XL, NESP55, A/B and Gsα) characterized by their specific exon 1 and common exons 2-13. While Gαs is biallelically expressed in most tissues, XL is only expressed from the paternal allele. Maternally inherited, loss-of-function mutations affecting those GNAS exons that ...
