Genes affected

RBAK-RBAKDN (HGNC:42971): (RBAK-RBAKDN readthrough) This locus represents naturally occurring read-through transcription between the neighboring RBAK (RB-associated KRAB zinc finger) and LOC389458 (hypothetical LOC389458) genes on chromosome 7. The read-through transcript encodes a protein that shares sequence identity with the upstream gene product but its C-terminal region is distinct due to frameshifts relative to the downstream gene.

RNF216P1 (HGNC:33610): (ring finger protein 216 pseudogene 1)

ENSG00000288633 (HGNC:):

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.96).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.767 is higher than 0.05.
