RAI1

retinoic acid induced 1

protein-coding gene17p11.2Gene information

What does this gene do?

The RAI1 gene provides instructions for making a protein that is active in cells throughout the body, particularly nerve cells (neurons) in the brain. Located in the nucleus of the cell, the RAI1 protein helps control the activity (expression) of certain genes. Most of the genes regulated by RAI1 have not been identified. However, studies suggest that this protein controls the expression of several genes involved in daily (circadian) rhythms, such as the sleep-wake cycle. The RAI1 protein also appears to play a role in development of the brain and of bones in the head and face (craniofacial bones).

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: 2,683
Submissions for variants in or overlapping this gene: 4,510
Submissions explicitly reporting this gene: 4,335
Alleles reported pathogenic / likely pathogenic: 194
VariationIDs with uncertain significance: 995
VariationIDs with conflicting classifications: 218

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 RAI1?

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 194 alleles in RAI1 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 RAI1.

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