Genes affected

DUS4L (HGNC:21517): (dihydrouridine synthase 4 like) Predicted to enable tRNA dihydrouridine synthase activity. Predicted to be involved in tRNA dihydrouridine synthesis. [provided by Alliance of Genome Resources, Apr 2022]

DUS4L-BCAP29 (HGNC:54422): (DUS4L-BCAP29 readthrough) This locus represents naturally occurring readthrough transcription between the neighboring DUS4L (dihydrouridine synthase 4 like) and BCAP29 (B cell receptor associated protein 29) genes on chromosome 7. The readthrough transcript encodes a fusion protein that shares sequence identity with each individual gene product. [provided by RefSeq, Jul 2019]

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.316 is higher than 0.05.
