- Abstract:
- Epigenetic defects in the imprinted GNAS cluster are associated with pseudohypoparathyroidism type Ib. In two kindreds with this disorder, we now report deletions that remove the differentially methylated region encompassing exon NESP55 and exons 3 and 4 of the antisense transcript. When inherited from a female, either deletion abolishes all maternal GNAS imprints and derepresses maternally silenced transcripts, suggesting that the deleted region contains a cis-acting element that controls imprinting of the maternal GNAS allele.
