Genes affected

PDE4D (HGNC:8783): (phosphodiesterase 4D) This gene encodes one of four mammalian counterparts to the fruit fly 'dunce' gene. The encoded protein has 3',5'-cyclic-AMP phosphodiesterase activity and degrades cAMP, which acts as a signal transduction molecule in multiple cell types. This gene uses different promoters to generate multiple alternatively spliced transcript variants that encode functional proteins.[provided by RefSeq, Sep 2009]

• acrodysostosis 2 with or without hormone resistance

  Inheritance: AD Classification: DEFINITIVE, STRONG, MODERATE Submitted by: Labcorp Genetics (formerly Invitae), Ambry Genetics, G2P
• acrodysostosis

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet
• acrodysostosis with multiple hormone resistance

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet
• chromosome 5q12 deletion syndrome

  Inheritance: Unknown Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.02).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.548 is higher than 0.05.
