Genes affected

NPR2 (HGNC:7944): (natriuretic peptide receptor 2) 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]

This sequence change replaces glutamine, which is neutral and polar, with glutamic acid, which is acidic and polar, at codon 417 of the NPR2 protein (p.Gln417Glu). This variant is present in population databases (rs796065356, gnomAD no frequency). This missense change has been observed in individual(s) with short stature (PMID: 24471569, 30602027). ClinVar contains an entry for this variant (Variation ID: 208360). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C25"). Experimental studies have shown that this missense change affects NPR2 function (PMID: 24471569). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
