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.91A>G (p.T31A) alteration is located in exon 3 (coding exon 2) of the BAK1 gene. This alteration results from a A to G substitution at nucleotide position 91, causing the threonine (T) at amino acid position 31 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
