AGPAT2

1-acylglycerol-3-phosphate O-acyltransferase 2

protein-coding gene9q34.3Gene information

What does this gene do?

The AGPAT2 gene provides instructions for making an enzyme that is found in many of the body's cells and tissues. It plays a critical role in the growth and development of adipocytes, which are cells that store fats for energy. Adipocytes are the major component of the body's fatty (adipose) tissue.

The AGPAT2 enzyme is part of a chemical pathway in many cells that produces two important types of fats (lipids): glycerophospholipids and triacylglycerols. Glycerophospholipids are the major component of cell membranes and are involved in chemical signaling within cells. Triacylglycerols (also known as triglycerides) are fat molecules that are stored in adipocytes for later conversion to energy.

The AGPAT2 enzyme is responsible for a particular chemical reaction in the production of these two types of lipids. Specifically, the enzyme helps convert a molecule called lysophosphatidic acid (LPA) to another molecule, phosphatidic acid (PA). Additional reactions convert phosphatidic acid to glycerophospholipids and triacylglycerols.

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: 388
Submissions for variants in or overlapping this gene: 661
Submissions explicitly reporting this gene: 558
Alleles reported pathogenic / likely pathogenic: 37
VariationIDs with uncertain significance: 150
VariationIDs with conflicting classifications: 23

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 AGPAT2?

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 37 alleles in AGPAT2 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 AGPAT2.

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