Genes affected
PDE7B (HGNC:8792): (phosphodiesterase 7B) The 3',5'-cyclic nucleotides cAMP and cGMP function as second messengers in a wide variety of signal transduction pathways. 3',5'-cyclic nucleotide phosphodiesterases (PDEs) catalyze the hydrolysis of cAMP and cGMP to the corresponding 5'-monophosphates and provide a mechanism to downregulate cAMP and cGMP signaling. This gene encodes a cAMP-specific phosphodiesterase, a member of the cyclic nucleotide phosphodiesterase family.[provided by RefSeq, Apr 2009]
PDE7B-AS1 (HGNC:56334): (PDE7B antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 18, 2023The c.676A>G (p.I226V) alteration is located in exon 8 (coding exon 8) of the PDE7B gene. This alteration results from a A to G substitution at nucleotide position 676, causing the isoleucine (I) at amino acid position 226 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
