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]

HOXB-AS1 (HGNC:43744): (HOXB cluster antisense RNA 1)

HOXB-AS3 (HGNC:40283): (HOXB cluster antisense RNA 3)

ACMG classification

Our verdict: Likely_benign. The variant received -6 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.21171433).
• BS2: High AC in GnomAdExome4 at 6 AD gene.
