Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the PTH1R 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.

Variant type	Pathogenic	Likely pathogenic	VUS	Likely benign	Benign	Sum

• Function: FUNCTION: Receptor for parathyroid hormone and for parathyroid hormone-related peptide. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase and also a phosphatidylinositol-calcium second messenger system. {ECO:0000269|PubMed:20172855, ECO:0000269|PubMed:27160269, ECO:0000269|PubMed:8397094}.
• Disease: DISEASE: Jansen metaphyseal chondrodysplasia (JMC) [MIM:156400]: Rare autosomal dominant disorder characterized by a short-limbed dwarfism associated with hypercalcemia and normal or low serum concentrations of the two parathyroid hormones. {ECO:0000269|PubMed:10487664, ECO:0000269|PubMed:15240651, ECO:0000269|PubMed:27160269, ECO:0000269|PubMed:7701349, ECO:0000269|PubMed:8703170, ECO:0000269|PubMed:9178745}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Chondrodysplasia Blomstrand type (BOCD) [MIM:215045]: Severe skeletal dysplasia. {ECO:0000269|PubMed:9745456}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Enchondromatosis multiple (ENCHOM) [MIM:166000]: A condition characterized by multiple formation of enchondromas, benign neoplasms derived from mesodermal cells that form cartilage. Enchondromas remain within the substance of a cartilage or bone. Clinical problems caused by enchondromas include skeletal deformity and the potential for malignant change to osteosarcoma. {ECO:0000269|PubMed:11850620}. Note=The disease may be caused by mutations affecting the gene represented in this entry.; DISEASE: Eiken skeletal dysplasia (EISD) [MIM:600002]: A rare skeletal dysplasia characterized by severely retarded ossification, principally of the epiphyses, pelvis, hands and feet, as well as by abnormal modeling of the bones in hands and feet, abnormal persistence of cartilage in the pelvis and mild growth retardation. {ECO:0000269|PubMed:15525660}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Primary failure of tooth eruption (PFE) [MIM:125350]: Rare condition that has high penetrance and variable expressivity and in which tooth retention occurs without evidence of any obvious mechanical interference. Instead, malfunction of the eruptive mechanism itself appears to cause nonankylosed permanent teeth to fail to erupt, although the eruption pathway has been cleared by bone resorption. {ECO:0000269|PubMed:19061984}. Note=The disease is caused by mutations affecting the gene represented in this entry.
