Genes affected

ENDOU (HGNC:14369): (endonuclease, poly(U) specific) This gene encodes a protein with endoribonuclease activity that binds polyuridine-enriched single-stranded RNA. This gene was initially characterized based on its high expression in placenta but was mischaracterized as a serine protease. In mouse, this gene promotes tolerance to self-antigens by regulating B cell activation-induced cell death (AICD). The protein may be useful as a tumor marker. Multiple alternatively spliced transcript variants encoding distinct protein isoforms have been found for this gene. [provided by RefSeq, Jul 2020]

RPAP3-DT (HGNC:55477): (RPAP3 divergent transcript)

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: This place is a probable branch point but likely benign (scored 0 / 10). Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.985 is higher than 0.05.
