Genes affected

TCP10L (HGNC:11657): (t-complex 10 like) Enables several functions, including identical protein binding activity; protein self-association; and transcription corepressor activity. Involved in negative regulation of transcription by RNA polymerase II. Located in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

CFAP298-TCP10L (HGNC:54636): (CFAP298-TCP10L readthrough) This locus represents naturally occurring readthrough transcription between the neighboring chromosome 21 open reading frame 59 (C21orf59) and TCP10L (t-complex 10 like) genes on chromosome 21. Readthrough transcripts may encode a fusion protein that shares sequence identity with each individual gene product. [provided by RefSeq, Apr 2017]

ACMG classification

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

• BP4: Computational evidence support a benign effect (MetaRNN=0.004184574).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.277 is higher than 0.05.
