Genes affected

PDE3A (HGNC:8778): (phosphodiesterase 3A) This gene encodes a member of the cGMP-inhibited cyclic nucleotide phosphodiesterase (cGI-PDE) family. cGI-PDE enzymes hydrolyze both cAMP and cGMP, and play critical roles in many cellular processes by regulating the amplitude and duration of intracellular cyclic nucleotide signals. The encoded protein mediates platelet aggregation and also plays important roles in cardiovascular function by regulating vascular smooth muscle contraction and relaxation. Inhibitors of the encoded protein may be effective in treating congestive heart failure. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

Collection Method: clinical testing

The c.46C>T (p.H16Y) alteration is located in exon 1 (coding exon 1) of the PDE3A gene. This alteration results from a C to T substitution at nucleotide position 46, causing the histidine (H) at amino acid position 16 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
