Genes affected

PDE5A (HGNC:8784): (phosphodiesterase 5A) This gene encodes a cGMP-binding, cGMP-specific phosphodiesterase, a member of the cyclic nucleotide phosphodiesterase family. This phosphodiesterase specifically hydrolyzes cGMP to 5'-GMP. It is involved in the regulation of intracellular concentrations of cyclic nucleotides and is important for smooth muscle relaxation in the cardiovascular system. Alternative splicing of this gene results in three transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2008]

The c.2455G>C (p.G819R) alteration is located in exon 20 (coding exon 20) of the PDE5A gene. This alteration results from a G to C substitution at nucleotide position 2455, causing the glycine (G) at amino acid position 819 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
