Genes affected

RAB4B-EGLN2 (HGNC:44465): (RAB4B-EGLN2 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring RAB4B (RAB4B, member RAS oncogene family) and EGLN2 (egl nine homolog 2) genes on chromosome 19. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus unlikely to produce a protein product. [provided by RefSeq, Feb 2011]

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.832 is higher than 0.05.
