Genes affected

PDE4B (HGNC:8781): (phosphodiesterase 4B) This gene is a member of the type IV, cyclic AMP (cAMP)-specific, cyclic nucleotide phosphodiesterase (PDE) family. The encoded protein regulates the cellular concentrations of cyclic nucleotides and thereby play a role in signal transduction. Altered activity of this protein has been associated with schizophrenia and bipolar affective disorder. Alternative splicing and the use of alternative promoters results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2014]

The c.2066C>T (p.S689F) alteration is located in exon 17 (coding exon 16) of the PDE4B gene. This alteration results from a C to T substitution at nucleotide position 2066, causing the serine (S) at amino acid position 689 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
