Genes affected

GUCY1A1 (HGNC:4685): (guanylate cyclase 1 soluble subunit alpha 1) 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. Several transcript variants encoding a few different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.
