This is a list of variants' phenotypes submitted to ClinVar and linked to the GPR101 gene.

Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the GPR101 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Orphan receptor.
• Disease: DISEASE: Pituitary adenoma 2, growth hormone-secreting (PITA2) [MIM:300943]: A form of pituitary adenoma, a neoplasm of the pituitary gland and one of the most common neuroendocrine tumors. Pituitary adenomas are clinically classified as functional and non-functional tumors, and manifest with a variety of features, including local invasion of surrounding structures and excessive hormone secretion. Functional pituitary adenomas are further classified by the type of hormone they secrete. PITA2 is a growth hormone-secreting benign neoplasm, also known as somatotropinoma. It clinically results in acromegaly, a condition characterized by coarse facial features, protruding jaw, and enlarged extremities. Excessive production of growth hormone in children or adolescents before the closure of epiphyses causes gigantism, a condition characterized by abnormally tall stature. {ECO:0000269|PubMed:25470569}. Note=The disease is caused by mutations affecting the gene represented in this entry.
