DCC

DCC netrin 1 receptor

protein-coding gene18q21.2Gene information

What does this gene do?

The DCC gene provides instructions for making a protein called the netrin-1 receptor, which is involved in the development of the nervous system. This protein attaches (binds) to a protein called netrin-1, and these two proteins fit together like a lock and key. The binding of netrin-1 to its receptor helps direct the growth of specialized nerve cell extensions called axons. Axons transmit nerve impulses that can signal muscle movement.

When the brain sends a signal to trigger muscle movement, the signal usually travels from one half of the brain to the opposite side of the body. The binding of netrin-1 to its receptor allows axons to develop this signaling pathway.

The netrin-1 receptor is also thought to act as a dependence receptor, which means it functions differently depending on whether or not it is bound to its protein. When the netrin-1 receptor is bound to netrin-1, it plays a role in nervous system development. When it is not bound to netrin-1, the netrin-1 receptor acts as a tumor suppressor, which means that it keeps cells from growing and dividing too fast or in an uncontrolled way. When the netrin-1 receptor is acting as a tumor suppressor, studies suggest that the netrin-1 receptor triggers the self-destruction of cells when they are no longer needed (apoptosis).

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: 460
Submissions for variants in or overlapping this gene: 571
Submissions explicitly reporting this gene: 468
Alleles reported pathogenic / likely pathogenic: 74
VariationIDs with uncertain significance: 223
VariationIDs with conflicting classifications: 6

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 DCC?

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 74 alleles in DCC 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 DCC.

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