MYBPC1

myosin binding protein C1

protein-coding gene12q23.2Gene information

What does this gene do?

The MYBPC1 gene provides instructions for making one version of a protein called myosin binding protein C. Several versions of myosin binding protein C are produced from different genes; these proteins are found in muscles used for movement (skeletal muscles) and in heart (cardiac) muscle. The version produced from the MYBPC1 gene, which is known as the slow skeletal isoform, is found primarily in skeletal muscles.

The slow isoform of myosin binding protein C is active during the development of skeletal muscles. Researchers believe that this protein helps regulate the tensing of muscle fibers (muscle contraction). Myosin binding protein C interacts with other muscle proteins, including myosin, actin, and titin. These proteins play essential roles in muscle cell structures called sarcomeres, which generate the mechanical force needed for muscles to contract. Studies suggest that myosin binding protein C contributes to the stability and maintenance of sarcomeres.

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: 511
Submissions for variants in or overlapping this gene: 815
Submissions explicitly reporting this gene: 773
Alleles reported pathogenic / likely pathogenic: 17
VariationIDs with uncertain significance: 228
VariationIDs with conflicting classifications: 17

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 MYBPC1?

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 17 alleles in MYBPC1 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 MYBPC1.

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