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 Likely_pathogenic. Variant got 6 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). The gene has 31 curated pathogenic missense variants (we use a threshold of 10). The gene has 9 curated benign missense variants. GenCC has associacion of the gene with short stature with nonspecific skeletal abnormalities, acromesomelic dysplasia 1, Maroteaux type, tall stature-scoliosis-macrodactyly of the great toes syndrome.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.913

PP5

Variant 9-35805586-C-T is Pathogenic according to our data. Variant chr9-35805586-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 143054.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr9-35805586-C-T is described in Lovd as [Pathogenic].
