What is the official name of the LPIN2 gene?

The official name of this gene is “lipin 2.”

LPIN2 is the gene's official symbol. The LPIN2 gene is also known by other names, listed below.

What is the normal function of the LPIN2 gene?

The LPIN2 gene provides instructions for producing a protein called lipin-2. Researchers believe that this protein may play a role in the processing of fats (lipid metabolism). It may also be involved in controlling inflammation and in cell division.

How are changes in the LPIN2 gene related to health conditions?

Majeed syndrome - caused by mutations in the LPIN2 gene

At least three mutations in the LPIN2 gene have been identified in people with Majeed syndrome. These mutations alter the structure and function of lipin-2, leading to chronic, abnormal inflammation in some of the body's tissues. It is unclear how LPIN2 gene mutations lead to the specific features of Majeed syndrome, including bone disease, a shortage of red blood cells (anemia), and inflammatory skin disorders.

Where is the LPIN2 gene located?

Cytogenetic Location: 18p11.31

Molecular Location on chromosome 18: base pairs 2,916,994 to 3,013,315

(Homo sapiens Annotation Release 107, GRCh38.p2) (NCBI (

The LPIN2 gene is located on the short (p) arm of chromosome 18 at position 11.31.

The LPIN2 gene is located on the short (p) arm of chromosome 18 at position 11.31.

More precisely, the LPIN2 gene is located from base pair 2,916,994 to base pair 3,013,315 on chromosome 18.
