TECTA

tectorin alpha

protein-coding gene11q23.3Gene information

What does this gene do?

The TECTA gene provides instructions for making a protein called alpha-tectorin. This protein is found in the tectorial membrane, which is part of a snail-shaped structure called the cochlea in the inner ear. The cochlea converts sound waves into nerve impulses, which are then transmitted to the brain. This process is critical for normal hearing.

Alpha-tectorin is large protein with multiple regions (called domains) through which it interacts with other proteins. These interactions are critical for the normal formation of the tectorial membrane.

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: 1,565
Submissions for variants in or overlapping this gene: 2,993
Submissions explicitly reporting this gene: 2,866
Alleles reported pathogenic / likely pathogenic: 146
VariationIDs with uncertain significance: 842
VariationIDs with conflicting classifications: 154

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 TECTA?

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 146 alleles in TECTA 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 TECTA.

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