Genes affected

HOXB3 (HGNC:5114): (homeobox B3) 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 a distinct biologic subset of acute myeloid leukemia (AML). [provided by RefSeq, Jul 2008]

Dec 18, 2023

The c.1024G>A (p.G342R) alteration is located in exon 4 (coding exon 2) of the HOXB3 gene. This alteration results from a G to A substitution at nucleotide position 1024, causing the glycine (G) at amino acid position 342 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
