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

May 11, 2022

The c.1282G>A (p.A428T) alteration is located in exon 10 (coding exon 10) of the PDE4A gene. This alteration results from a G to A substitution at nucleotide position 1282, causing the alanine (A) at amino acid position 428 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
