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=0.16159788).

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 01, 2022The c.1450A>G (p.I484V) alteration is located in exon 11 (coding exon 11) of the PRKG2 gene. This alteration results from a A to G substitution at nucleotide position 1450, causing the isoleucine (I) at amino acid position 484 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
