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.2404A>T (p.T802S) alteration is located in exon 19 (coding exon 19) of the PDE5A gene. This alteration results from a A to T substitution at nucleotide position 2404, causing the threonine (T) at amino acid position 802 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
