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)

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.77).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.733 is higher than 0.05.
