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]

The c.3621C>G (p.D1207E) alteration is located in exon 25 (coding exon 25) of the ATAD2 gene. This alteration results from a C to G substitution at nucleotide position 3621, causing the aspartic acid (D) at amino acid position 1207 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
