• Clinical Significance: Uncertain significance criteria provided, single submitter U:1
• Conservation: PhyloP100: 8.72

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 Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.32042706).

The c.2759C>G (p.P920R) alteration is located in exon 20 (coding exon 20) of the ATAD2B gene. This alteration results from a C to G substitution at nucleotide position 2759, causing the proline (P) at amino acid position 920 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
