TFAP2B

transcription factor AP-2 beta

protein-coding gene6p12.3Gene information

What does this gene do?

The TFAP2B gene provides instructions for making a protein called transcription factor AP-2β. A transcription factor is a protein that attaches (binds) to specific regions of DNA and helps control the activity of particular genes. Transcription factor AP-2β is one of a group of related proteins called AP-2 transcription factors. These proteins regulate genes that help control cell division and the self-destruction of cells that are no longer needed (apoptosis).

Transcription factor AP-2β is involved in development before birth. In particular, this protein is active in the neural crest, which is a group of cells in the early embryo that give rise to many tissues and organs. Neural crest cells migrate to form portions of the nervous system, glands that produce hormones (endocrine glands), pigment cells, smooth muscle and other tissues in the heart, and many tissues in the face and skull. Transcription factor AP-2β also appears to play an important role in the development of the limbs.

ClinGen reviews

ClinGen reviews the evidence linking a particular gene to a condition. Each rating below describes the strength of that link. It does not classify a variant in your DNA file.

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: 218
Submissions for variants in or overlapping this gene: 273
Submissions explicitly reporting this gene: 247
Alleles reported pathogenic / likely pathogenic: 32
VariationIDs with uncertain significance: 99
VariationIDs with conflicting classifications: 3

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 TFAP2B?

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 32 alleles in TFAP2B 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 TFAP2B.

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