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 Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 4-155711210-C-T is Pathogenic according to our data. Variant chr4-155711210-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 127095.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr4-155711210-C-T is described in Lovd as [Pathogenic].
