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

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the NPR2 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 31 curated pathogenic missense variants (we use a threshold of 10). The gene has 9 curated benign missense variants. Gene score misZ: 2.9586 (below the threshold of 3.09). Trascript score misZ: 4.5861 (above the threshold of 3.09). GenCC associations: The gene is linked to short stature with nonspecific skeletal abnormalities, acromesomelic dysplasia 1, Maroteaux type, tall stature-scoliosis-macrodactyly of the great toes syndrome.
• BP4: Computational evidence support a benign effect (MetaRNN=0.08097908).
