Target Information

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