Genes affected

HOXB2 (HGNC:5113): (homeobox B2) This gene is a member of the Antp homeobox family and encodes a nuclear protein with a homeobox DNA-binding domain. It is included in a cluster of homeobox B genes located on chromosome 17. The encoded protein functions as a sequence-specific transcription factor that is involved in development. Increased expression of this gene is associated with pancreatic cancer. [provided by RefSeq, Jul 2008]

The c.865C>T (p.P289S) alteration is located in exon 2 (coding exon 2) of the HOXB2 gene. This alteration results from a C to T substitution at nucleotide position 865, causing the proline (P) at amino acid position 289 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
