Genes affected

EBLN2 (HGNC:25493): (endogenous Bornavirus like nucleoprotein 2)

PPP4R2 (HGNC:18296): (protein phosphatase 4 regulatory subunit 2) The protein encoded by this gene is a regulatory subunit of the serine/threonine-protein phosphatase 4 complex. In addition to being required for efficient DNA double strand break repair, this complex plays a role in organization of microtubules at centrosomes and processing of spliceosomal snRNPs. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2015]

ACMG classification

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

• BP4: Computational evidence support a benign effect (MetaRNN=2.131463E-5).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.615 is higher than 0.05.
