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]

Jul 12, 2022

The c.614G>A (p.R205Q) alteration is located in exon 2 (coding exon 2) of the HOXB2 gene. This alteration results from a G to A substitution at nucleotide position 614, causing the arginine (R) at amino acid position 205 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
