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.

Ambry Genetics

Dec 15, 2022

The c.1265C>T (p.S422F) alteration is located in exon 10 (coding exon 10) of the PRKG2 gene. This alteration results from a C to T substitution at nucleotide position 1265, causing the serine (S) at amino acid position 422 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
