CLPB

ClpB family mitochondrial disaggregase

protein-coding gene11q13.4Gene information

What does this gene do?

The CLPB gene provides instructions for making a protein whose function is unknown. The CLPB protein is found in cells throughout the body but is most abundant in the brain. Based on its similarity to a protein in other organisms, researchers speculate that the CLPB protein helps unfold misfolded proteins so they can be refolded correctly. When misfolded, proteins cannot function properly and may be damaging to cells.

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: 948
Submissions for variants in or overlapping this gene: 1,449
Submissions explicitly reporting this gene: 1,406
Alleles reported pathogenic / likely pathogenic: 61
VariationIDs with uncertain significance: 455
VariationIDs with conflicting classifications: 34

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 CLPB?

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 61 alleles in CLPB 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 CLPB.

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