Genes affected

PRKG1 (HGNC:9414): (protein kinase cGMP-dependent 1) Mammals have three different isoforms of cyclic GMP-dependent protein kinase (Ialpha, Ibeta, and II). These PRKG isoforms act as key mediators of the nitric oxide/cGMP signaling pathway and are important components of many signal transduction processes in diverse cell types. This PRKG1 gene on human chromosome 10 encodes the soluble Ialpha and Ibeta isoforms of PRKG by alternative transcript splicing. A separate gene on human chromosome 4, PRKG2, encodes the membrane-bound PRKG isoform II. The PRKG1 proteins play a central role in regulating cardiovascular and neuronal functions in addition to relaxing smooth muscle tone, preventing platelet aggregation, and modulating cell growth. This gene is most strongly expressed in all types of smooth muscle, platelets, cerebellar Purkinje cells, hippocampal neurons, and the lateral amygdala. Isoforms Ialpha and Ibeta have identical cGMP-binding and catalytic domains but differ in their leucine/isoleucine zipper and autoinhibitory sequences and therefore differ in their dimerization substrates and kinase enzyme activity.

The p.N369S variant (also known as c.1106A>G), located in coding exon 10 of the PRKG1 gene, results from an A to G substitution at nucleotide position 1106. The asparagine at codon 369 is replaced by serine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species; however, serine is the reference amino acid in other vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. In addition, this alteration is predicted to create a new alternate splice acceptor site by the BDGP and ESE finder in silico models; however experimental evidence is not available. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 369 of the PRKG1 protein (p.Asn369Ser). This variant is present in population databases (rs775372704, gnomAD 0.009%). This variant has not been reported in the literature in individuals affected with PRKG1-related conditions. ClinVar contains an entry for this variant (Variation ID: 451057). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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. -

GeneDx

Aug 02, 2017

A variant of uncertain significance has been identified in the PRKG1 gene. The N369S variant has not been published as pathogenic or been reported as benign to our knowledge. This variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). Nevertheless, the N369S variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. Additionally, this substitution occurs at a position not conserved. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. -
