Genes affected

PRKG2 (HGNC:9416): (protein kinase cGMP-dependent 2) This gene encodes a protein that belongs to the serine/threonine protein kinase family of proteins. The encoded protein binds to and inhibits the activation of several receptor tyrosine kinases. The membrane-bound protein is a regulator of intestinal secretion, bone growth and renin secretion. Alternate splicing results in multiple transcript variants encoding distinct isoforms whose regulatory N-termini differ in length but whose C-terminal catalytic domains are identical.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 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), PRKG2. . Gene score misZ 2.9899 (greater than the threshold 3.09). Trascript score misZ 3.189 (greater than threshold 3.09). GenCC has associacion of gene with acromesomelic dysplasia 4.

BP4

Computational evidence support a benign effect (MetaRNN=0.18146199).

The c.1325C>A (p.A442D) alteration is located in exon 10 (coding exon 10) of the PRKG2 gene. This alteration results from a C to A substitution at nucleotide position 1325, causing the alanine (A) at amino acid position 442 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
