Genes affected

BOK (HGNC:1087): (BCL2 family apoptosis regulator BOK) The protein encoded by this gene belongs to the BCL2 family, members of which form homo- or heterodimers, and act as anti- or proapoptotic regulators that are involved in a wide variety of cellular processes. Studies in rat show that this protein has restricted expression in reproductive tissues, interacts strongly with some antiapoptotic BCL2 proteins, not at all with proapoptotic BCL2 proteins, and induces apoptosis in transfected cells. Thus, this protein represents a proapoptotic member of the BCL2 family. [provided by RefSeq, Sep 2011]

Collection Method: clinical testing

The c.371T>C (p.V124A) alteration is located in exon 4 (coding exon 3) of the BOK gene. This alteration results from a T to C substitution at nucleotide position 371, causing the valine (V) at amino acid position 124 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
