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]

ACMG classification
Classification made for transcript
Verdict is Uncertain_significance. Variant got 3 ACMG points.
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), NPR2. . Gene score misZ 2.9586 (greater than the threshold 3.09). Trascript score misZ 4.5861 (greater than threshold 3.09). GenCC has associacion of gene with short stature with nonspecific skeletal abnormalities, acromesomelic dysplasia 1, Maroteaux type, tall stature-scoliosis-macrodactyly of the great toes syndrome.

Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Jun 05, 2022 | 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. 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: "Possibly Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 1428049). This variant has not been reported in the literature in individuals affected with NPR2-related conditions. This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 29 of the NPR2 protein (p.Val29Met). This variant is not present in population databases (gnomAD no frequency). - |
