Genes affected

PBXIP1 (HGNC:21199): (PBX homeobox interacting protein 1) The protein encoded by this gene interacts with the PBX1 homeodomain protein, inhibiting its transcriptional activation potential by preventing its binding to DNA. The encoded protein, which is primarily cytosolic but can shuttle to the nucleus, also can interact with estrogen receptors alpha and beta and promote the proliferation of breast cancer, brain tumors, and lung cancer. Several transcript variants encoding different isoforms have been found for this gene. More variants exist, but their full-length natures have yet to be determined. [provided by RefSeq, Dec 2015]

Collection Method: clinical testing

The c.1964G>A (p.R655H) alteration is located in exon 10 (coding exon 9) of the PBXIP1 gene. This alteration results from a G to A substitution at nucleotide position 1964, causing the arginine (R) at amino acid position 655 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
