Genes affected

BIK (HGNC:1051): (BCL2 interacting killer) The protein encoded by this gene shares a critical BH3 domain with other death-promoting proteins, such as BID, BAK, BAD and BAX, that is required for its pro-apoptotic activity, and for interaction with anti-apoptotic members of the BCL2 family, and viral survival-promoting proteins. Since the activity of this protein is suppressed in the presence of survival-promoting proteins, it is suggested as a likely target for anti-apoptotic proteins. [provided by RefSeq, Sep 2011]

Collection Method: clinical testing

The c.224C>A (p.P75Q) alteration is located in exon 3 (coding exon 2) of the BIK gene. This alteration results from a C to A substitution at nucleotide position 224, causing the proline (P) at amino acid position 75 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
