Target Information

Mutations in the GNAS gene result in pseudohypoparathyroidism type 1a and 1b, Albright hereditary osteodystrophy, pseudopseudohypoparathyroidism, McCune-Albright syndrome, progressive osseous heteroplasia, polyostotic fibrous dysplasia of bone, and some pituitary tumors.
This gene exhibits a complex imprinted expression pattern, encoding maternally, paternally, and biallelically expressed proteins derived from alternatively spliced transcripts. Each upstream exon lies within a differentially methylated region, typical of imprinted genes.
The close proximity (14 kb) of two oppositely expressed promoter regions is unusual. One alternate 5′ exon introduces a frameshift, yielding an isoform structurally unrelated to the others. An antisense transcript may regulate imprinting in this region.
Mutations in this gene cause pseudohypoparathyroidism type 1a (PHP1a), showing atypical autosomal dominant inheritance requiring maternal transmission for full penetrance.
