Gene Information

This locus has a highly complex imprinted expression pattern. It gives rise to maternally paternally and biallelically expressed transcripts that are derived from four alternative promoters and 5' exons. Some transcripts contains a differentially methylated region (DMR) at their 5' exons and this DMR is commonly found in imprinted genes and correlates with transcript expression. An antisense transcript is produced from an overlapping locus on the opposite strand. One of the transcripts produced from this locus and the antisense transcript are paternally expressed noncoding RNAs and may regulate imprinting in this region. In addition one of the transcripts contains a second overlapping ORF which encodes a structurally unrelated protein - Alex. Alternative splicing of downstream exons is also observed which results in different forms of the stimulatory G-protein alpha subunit a key element of the classical signal transduction pathway linking receptor-ligand interactions with the activation of adenylyl cyclase and a variety of cellular reponses. Multiple transcript variants encoding different isoforms have been found for this gene. Mutations in this gene result in pseudohypoparathyroidism type 1a pseudohypoparathyroidism type 1b Albright hereditary osteodystrophy pseudopseudohypoparathyroidism McCune-Albright syndrome progressive osseus heteroplasia polyostotic fibrous dysplasia of bone and some pituitary tumors.
