natriuretic peptide receptor 2, the group of Transmembrane guanylate cyclases|DENN domain containing

Gene summary

This gene encodes natriuretic peptide receptor B, one of two integral membrane receptors for natriuretic peptides. Both NPR1 and NPR2 contain five functional domains: an extracellular ligand-binding domain, a single membrane-spanning region, and intracellularly a protein kinase homology domain, a helical hinge region involved in oligomerization, and a carboxyl-terminal guanylyl cyclase catalytic domain. The protein is the primary receptor for C-type natriuretic peptide (CNP), which upon ligand binding exhibits greatly increased guanylyl cyclase activity. Mutations in this gene are the cause of acromesomelic dysplasia Maroteaux type. [provided by RefSeq, Jul 2008]

ClinVar Variants & Pathogenicity by Type

Statistics based on transcript NM_003995.4. Only rare variants are included.

We include only reliable ClinVar variants with their consequences to MANE Select, MANE Plus Clinical transcripts, or transcripts with TSL equal to 1. Click a count to filter the variants table below.

Slight differences between displayed counts and ClinVar may occur due to a different transcript/consequence chosen by our variant effect predictor, or because we classify Benign/Likely benign as Likely benign and Pathogenic/Likely pathogenic as Likely pathogenic.

Function
FUNCTION: Receptor for the C-type natriuretic peptide NPPC/CNP hormone. Has guanylate cyclase activity upon binding of its ligand. May play a role in the regulation of skeletal growth. {ECO:0000269|PubMed:15146390, ECO:0000269|PubMed:1672777, ECO:0000269|PubMed:24001744, ECO:0000269|PubMed:24471569, ECO:0000269|PubMed:26980729}.;
Disease
DISEASE: Acromesomelic dysplasia, Maroteaux type (AMDM) [MIM:602875]: An autosomal recessive acromesomelic chondrodysplasia. Acromesomelic chondrodysplasias are rare hereditary skeletal disorders characterized by short stature, very short limbs and hand/foot malformations. The severity of limb abnormalities increases from proximal to distal with profoundly affected hands and feet showing brachydactyly and/or rudimentary fingers (knob-like fingers). AMDM is characterized by axial skeletal involvement with wedging of vertebral bodies. In AMDM all skeletal elements are present but show abnormal rates of linear growth. {ECO:0000269|PubMed:15146390, ECO:0000269|PubMed:17652215, ECO:0000269|PubMed:26980729}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Epiphyseal chondrodysplasia, Miura type (ECDM) [MIM:615923]: An overgrowth syndrome characterized by tall stature, long hands and feet with arachnodactyly, macrodactyly of the great toes, scoliosis, coxa valga and slipped capital femoral epiphysis. {ECO:0000269|PubMed:22870295, ECO:0000269|PubMed:23827346, ECO:0000269|PubMed:24057292, ECO:0000269|PubMed:24259409}.
