Genes affected

ATAD2 (HGNC:30123): (ATPase family AAA domain containing 2) A large family of ATPases has been described, whose key feature is that they share a conserved region of about 220 amino acids that contains an ATP-binding site. The proteins that belong to this family either contain one or two AAA (ATPases Associated with diverse cellular Activities) domains. AAA family proteins often perform chaperone-like functions that assist in the assembly, operation, or disassembly of protein complexes. The protein encoded by this gene contains two AAA domains, as well as a bromodomain. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.26001036).

Collection Method: clinical testing

The c.3909G>T (p.Q1303H) alteration is located in exon 26 (coding exon 26) of the ATAD2 gene. This alteration results from a G to T substitution at nucleotide position 3909, causing the glutamine (Q) at amino acid position 1303 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
