Genes affected

GUCY1A2 (HGNC:4684): (guanylate cyclase 1 soluble subunit alpha 2) Soluble guanylate cyclases are heterodimeric proteins that catalyze the conversion of GTP to 3',5'-cyclic GMP and pyrophosphate. The protein encoded by this gene is an alpha subunit of this complex and it interacts with a beta subunit to form the guanylate cyclase enzyme, which is activated by nitric oxide. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]

The c.556G>A (p.E186K) alteration is located in exon 4 (coding exon 4) of the GUCY1A2 gene. This alteration results from a G to A substitution at nucleotide position 556, causing the glutamic acid (E) at amino acid position 186 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
