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.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2024The c.1934C>T (p.T645M) alteration is located in exon 14 (coding exon 14) of the PRKG2 gene. This alteration results from a C to T substitution at nucleotide position 1934, causing the threonine (T) at amino acid position 645 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
