LIMK1

LIM domain kinase 1

protein-coding gene7q11.23Gene information

What does this gene do?

The LIMK1 gene provides instructions for making a protein that is highly active in the brain, where it is thought to be involved in the growth and development of nerve cells. Studies suggest that this protein may play an important role in areas of the brain that are responsible for processing visual-spatial information (visuospatial constructive cognition). These parts of the brain are important for visualizing an object as a set of parts and performing tasks such as writing, drawing, constructing models, and assembling puzzles.

Within cells, the LIMK1 protein likely regulates aspects of the cytoskeleton, the structural framework that helps to determine cell shape, size, and movement. The LIMK1 protein helps control the organization of actin filaments, which are long, thin fibers that are part of the cytoskeleton. Actin filaments are necessary for several normal cellular functions, such as cell division, cell movement (motility), maintenance of cell shape, transport of proteins and other molecules within cells, and chemical signaling between cells.

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: 323
Submissions for variants in or overlapping this gene: 376
Submissions explicitly reporting this gene: 202
Alleles reported pathogenic / likely pathogenic: 4
VariationIDs with uncertain significance: 83
VariationIDs with conflicting classifications: 1

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 LIMK1?

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 4 alleles in LIMK1 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 LIMK1.

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