BICD2

BICD cargo adaptor 2

protein-coding gene9q22.31Gene information

What does this gene do?

The BICD2 gene provides instructions for making one of a family of proteins called golgins. Golgins help maintain the structure of a cell component called the Golgi apparatus, in which newly produced proteins are modified so they can carry out their functions.

The BICD2 protein is found in all cells. The protein attaches (binds) to a group of proteins called the dynein complex, turning it on (activating it) and helping it bind to other cellular materials for transport. During transport, BICD2 stabilizes the dynein complex along a track-like system of small tubes called microtubules, similar to a conveyer belt. The BICD2 protein helps the dynein complex with protein transport, positioning of cell compartments, mobility of structures within the cell, and many other cell processes.

In nerve cells (neurons), the BICD2 protein helps the dynein complex transport sac-like structures called synaptic vesicles. These structures contain chemical messengers that allow neighboring cells to communicate with one another.

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: 1,020
Submissions for variants in or overlapping this gene: 1,561
Submissions explicitly reporting this gene: 1,510
Alleles reported pathogenic / likely pathogenic: 39
VariationIDs with uncertain significance: 439
VariationIDs with conflicting classifications: 70

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 BICD2?

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 39 alleles in BICD2 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 BICD2.

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