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]

PDE4A (HGNC:):

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.008137226).
• BP6: Variant 19-10457992-C-T is Benign according to our data. Variant chr19-10457992-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 445369.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.00288 (438/152256) while in subpopulation AMR AF= 0.0237 (362/15288). AF 95% confidence interval is 0.0217. There are 9 homozygotes in gnomad4. There are 221 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 438 AD gene.
