Genes affected

BCAP29 (HGNC:24131): (B cell receptor associated protein 29) Involved in osteoblast differentiation. Located in membrane. [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

Verdict is Likely_benign. Variant got -4 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.91).
