Duplications of GPR101 gene are associated with X-linked acrogigantism and acromegaly; 924 G>C mutation is associated with sporadic acromegaly
Title: Mutations in GPR101 as a potential cause of X-linked acrogigantism and acromegaly.
Germline or somatic microduplications of the Xq26.3 chromosomal region, invariably involving the GPR101 gene, constitute the genetic defect leading to X-Linked Acrogigantism. GPR101 encodes a class A G protein-coupled receptor that activates the 3',5'-cyclic adenosine monophosphate signaling pathway.
Title: An orphan G-protein-coupled receptor causes human gigantism and/or acromegaly: Molecular biology and clinical correlations.
This study shows that different GPR101 transcripts exist and that the brain is the major site of GPR101 expression across different species, although divergent species- and temporal-specific expression patterns are evident. These findings suggest an important role for GPR101 in brain and pituitary development and likely reflect the very different growth, development and maturation patterns among species.
Title: Characterization of GPR101 transcript structure and expression patterns.
Study showed that X-linked acrogigantism (XLAG) can result from germline or somatic duplication of GPR101. Duplication of GPR101 alone is sufficient for the development of XLAG, implicating it as the causative gene within the Xq26.3 region. The pathological features of XLAG-associated pituitary adenomas are typical and, together with the clinical phenotype, should prompt genetic testing.

Germline GPR101 mutations are very rare in patients with sporadic pituitary adenomas of various histotypes.
Title: Very low frequency of germline GPR101 genetic variation and no biallelic defects with AIP in a large cohort of patients with sporadic pituitary adenomas.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
