Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the NPR2 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: 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}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Short stature with non-specific skeletal abnormalities (SNSK) [MIM:616255]: A condition characterized by short stature, defined as a height less than 2 SD below normal, and no endocrine abnormalities. {ECO:0000269|PubMed:24001744, ECO:0000269|PubMed:24471569}.
