Genes affected

BMP8A (HGNC:21650): (bone morphogenetic protein 8a) This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. The encoded preproprotein is proteolytically processed to generate each subunit of the disulfide-linked homodimer. This protein may play a role in development of the reproductive system. This gene may have arose from a gene duplication event and its gene duplicate is also present on chromosome 1. [provided by RefSeq, Jul 2016]

PPIEL (HGNC:):

PPIEL (HGNC:33195): (peptidylprolyl isomerase E like (pseudogene)) This transcribed pseudogene is related to PPIE (Gene ID: 10450). Expression of this pseudogene may be downregulated in non-small cell lung cancer (NSCLC). Differential DNA methylation of this locus may be associated with intellectual disability and bipolar disorder in human patients. [provided by RefSeq, Sep 2016]

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.85).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.728 is higher than 0.05.
