Genes affected

BAK1 (HGNC:949): (BCL2 antagonist/killer 1) The protein encoded by this gene belongs to the BCL2 protein family. BCL2 family members form oligomers or heterodimers and act as anti- or pro-apoptotic regulators that are involved in a wide variety of cellular activities. This protein localizes to mitochondria, and functions to induce apoptosis. It interacts with and accelerates the opening of the mitochondrial voltage-dependent anion channel, which leads to a loss in membrane potential and the release of cytochrome c. This protein also interacts with the tumor suppressor P53 after exposure to cell stress. [provided by RefSeq, Jul 2008]

BAK1 links:

GGNBP1 (HGNC:19427): (gametogenetin binding protein 1 (pseudogene)) This gene is the ortholog of the mouse gametogenetin-binding protein 1 gene. In human, the open reading frame is disrupted by a nonsense mutation after 8-aa; consequently, this gene is currently considered to be a unitary pseudogene in human even though it is functional in other mammals.

The c.620G>C (p.R207T) alteration is located in exon 6 (coding exon 5) of the BAK1 gene. This alteration results from a G to C substitution at nucleotide position 620, causing the arginine (R) at amino acid position 207 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
