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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 30, 2022The c.1006G>A (p.A336T) 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 1006, causing the alanine (A) at amino acid position 336 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
