Genes affected

GUCY1B1 (HGNC:4687): (guanylate cyclase 1 soluble subunit beta 1) This gene encodes the beta subunit of the soluble guanylate cyclase (sGC), which catalyzes the conversion of GTP (guanosine triphosphate) to cGMP (cyclic guanosine monophosphate). The encoded protein contains an HNOX domain, which serves as a receptor for ligands such as nitric oxide, oxygen and nitrovasodilator drugs. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2014]

The c.901A>G (p.I301V) alteration is located in exon 8 (coding exon 8) of the GUCY1B3 gene. This alteration results from a A to G substitution at nucleotide position 901, causing the isoleucine (I) at amino acid position 301 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
