Genes affected

CHURC1-FNTB (HGNC:42960): (CHURC1-FNTB readthrough) This locus represents naturally occurring read-through transcription between the neighboring CHURC1 (churchill domain containing 1) and FNTB (farnesyltransferase, CAAX box, beta) on chromosome 14. The read-through transcript produces a fusion protein that shares sequence identity with each individual gene product. [provided by RefSeq, Feb 2011]

CHURC1 (HGNC:20099): (churchill domain containing 1) Predicted to enable zinc ion binding activity. Predicted to be involved in positive regulation of transcription, DNA-templated. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.91).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.401 is higher than 0.05.
