Genes affected
ATAD3B (HGNC:24007): (ATPase family AAA domain containing 3B) The protein encoded by this gene is localized to the mitochondrial inner membrane, where it can bind to a highly-related protein, ATAD3A. ATAD3A appears to interact with matrix nucleoid complexes, and the encoded protein negatively regulates that interaction. This gene is expressed almost exclusively in pluripotent embryonic stem cells and some cancer cells. Two transcript variants encoding different isoforms have been found for this gene.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 02, 2023The c.62C>T (p.P21L) alteration is located in exon 1 (coding exon 1) of the ATAD3B gene. This alteration results from a C to T substitution at nucleotide position 62, causing the proline (P) at amino acid position 21 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
