Genes affected

TDRD3 (HGNC:20612): (tudor domain containing 3) Enables chromatin binding activity; methylated histone binding activity; and transcription coactivator activity. Predicted to be involved in chromatin organization and positive regulation of transcription, DNA-templated. Located in Golgi apparatus; cytosol; and nucleoplasm. Colocalizes with exon-exon junction complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.94).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.344 is higher than 0.05.
