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.

The c.4102C>T (p.R1368C) alteration is located in exon 26 (coding exon 26) of the ATAD2B gene. This alteration results from a C to T substitution at nucleotide position 4102, causing the arginine (R) at amino acid position 1368 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
