BIN1

bridging integrator 1

protein-coding gene2q14.3Gene information

What does this gene do?

The BIN1 gene provides instructions for making a protein that is found in tissues throughout the body, where it interacts with a variety of other proteins. The BIN1 protein is thought to be involved in the transportation of materials from the cell surface into the cell (endocytosis) and the self-destruction of cells (apoptosis). The BIN1 protein may act as a tumor suppressor protein, which means it prevents cells from growing and dividing too rapidly or in an uncontrolled way.

Several different versions (isoforms) of the BIN1 protein are produced from the BIN1 gene. These isoforms vary by size and are active in different tissues. The BIN1 protein isoform that is expressed in muscle cells is thought to be involved in the formation of structures called transverse tubules or T tubules. These structures are found within the membrane of muscle cells, where they play a role in muscle tensing (contraction) and relaxation.

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: 892
Submissions for variants in or overlapping this gene: 1,388
Submissions explicitly reporting this gene: 1,348
Alleles reported pathogenic / likely pathogenic: 11
VariationIDs with uncertain significance: 383
VariationIDs with conflicting classifications: 45

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 BIN1?

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 11 alleles in BIN1 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 BIN1.

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