HOXB13

homeobox B13

protein-coding gene17q21.32Gene information

What does this gene do?

The HOXB13 gene provides instructions for producing a protein that attaches (binds) to specific regions of DNA and regulates the activity of other genes. On the basis of this role, the protein produced from the HOXB13 gene is called a transcription factor. The HOXB13 protein is part of a large group of transcription factors called the homeobox protein family. The HOXB13 protein is thought to play a role in the development and maintenance of the skin. It also acts as a tumor suppressor, which means that it keeps cells from growing and dividing too fast or in an uncontrolled way.

The HOXB13 protein has a characteristic homeobox region called the homeodomain, which binds to DNA, and two other regions called MEIS interacting domains. The MEIS interacting domains are thought to help regulate the activity of the HOXB13 protein by controlling the binding of the homeodomain with DNA.

ClinGen reviews

We found no matching ClinGen review in the data used here. This does not rule out a link between the gene and a condition.

ClinVar records

These numbers show what has been submitted to ClinVar. They cannot tell you how likely you are to have a condition.

Submitted alleles: 1,951
Submissions for variants in or overlapping this gene: 3,388
Submissions explicitly reporting this gene: 3,372
Alleles reported pathogenic / likely pathogenic: 2
VariationIDs with uncertain significance: 1,505
VariationIDs with conflicting classifications: 54

The rows count different things: alleles, submissions or VariationIDs. Their categories can overlap, so do not add them together. Pathogenic/likely pathogenic counts exclude structural variants that merely overlap a gene. A dash in the source means “not reported,” not zero.

NCBI produces the gene-summary file each week using counts recorded at the start of the month. The numbers may differ from those on the live ClinVar website. Read the field definitions ↗

YOUR DNA FILE

Can your DNA file tell you about HOXB13?

From a DNA test kit (such as 23andMe, AncestryDNA or MyHeritage). These kits check a fixed list of about 600,000 to 700,000 positions across your whole genome. ClinVar lists 2 alleles in HOXB13 reported as pathogenic or likely pathogenic. A kit checks only some of these positions, and often none of them.

From whole genome sequencing (a VCF file). Sequencing reads most of your genome. Your file lists the places where your DNA differs from the reference genome. Some regions are hard to sequence, including parts of some genes that have near-identical copies elsewhere, and a VCF file does not record which positions were read well.

If a variant is not in your file, that does not mean you don’t have it.

What BioDecode checks

BioDecode compares every variant in your file with ClinVar, on your own computer. For each match, it shows the ClinVar classification, the review status and the condition it was reported for. Your file is not uploaded.

A ClinVar classification applies to one particular variant and the condition it was reported for. It does not tell you about other variants in HOXB13.

BioDecode cannot fill gaps in your test, diagnose a condition or replace clinical testing.
