Genes affected

ATAD2B (HGNC:29230): (ATPase family AAA domain containing 2B) The protein encoded by this gene belongs to the AAA ATPase family. This family member includes an N-terminal bromodomain. It has been found to be localized to the nucleus, partly to replication sites, consistent with a chromatin-related function. Alternative splicing of this gene results in multiple transcript variants.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.03).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.766 is higher than 0.05.
