Genes affected

PDE4A (HGNC:8780): (phosphodiesterase 4A) The protein encoded by this gene belongs to the cyclic nucleotide phosphodiesterase (PDE) family, and PDE4 subfamily. This PDE hydrolyzes the second messenger, cAMP, which is a regulator and mediator of a number of cellular responses to extracellular signals. Thus, by regulating the cellular concentration of cAMP, this protein plays a key role in many important physiological processes. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.[provided by RefSeq, Jul 2011]

Ambry Genetics

Sep 16, 2021

The c.566G>A (p.R189Q) alteration is located in exon 4 (coding exon 4) of the PDE4A gene. This alteration results from a G to A substitution at nucleotide position 566, causing the arginine (R) at amino acid position 189 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
