Genes affected

VDAC3 (HGNC:12674): (voltage dependent anion channel 3) This gene encodes a voltage-dependent anion channel (VDAC), and belongs to the mitochondrial porin family. VDACs are small, integral membrane proteins that traverse the outer mitochondrial membrane and conduct ATP and other small metabolites. They are known to bind several kinases of intermediary metabolism, thought to be involved in translocation of adenine nucleotides, and are hypothesized to form part of the mitochondrial permeability transition pore, which results in the release of cytochrome c at the onset of apoptotic cell death. Alternatively transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Oct 2011]

The c.442G>A (p.E148K) alteration is located in exon 8 (coding exon 6) of the VDAC3 gene. This alteration results from a G to A substitution at nucleotide position 442, causing the glutamic acid (E) at amino acid position 148 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
