What is the official name of the SRCAP gene?

The official name of this gene is “Snf2-related CREBBP activator protein.”

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

What is the normal function of the SRCAP gene?

The SRCAP gene provides instructions for making a protein called Snf2-related CREBBP activator protein, or SRCAP. SRCAP is one of several proteins that help activate a gene called CREBBP. The protein produced from the CREBBP gene, called CREB binding protein, plays a key role in regulating cell growth and division and is important for normal development.

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

Floating-Harbor syndrome - caused by mutations in the SRCAP gene

At least five SRCAP gene mutations have been identified in people with Floating-Harbor syndrome, a disorder involving short stature, slowing of the mineralization of the bones (delayed bone age), delayed speech development, and characteristic facial features. The SRCAP gene mutations that cause Floating-Harbor syndrome may result in an altered protein that interferes with normal activation of the CREBBP gene, resulting in problems in development. However, the relationship between SRCAP gene mutations and the specific signs and symptoms of Floating-Harbor syndrome is unknown.

Where is the SRCAP gene located?

Cytogenetic Location: 16p11.2

Molecular Location on chromosome 16: base pairs 30,699,141 to 30,740,129

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

The SRCAP gene is located on the short (p) arm of chromosome 16 at position 11.2.

The SRCAP gene is located on the short (p) arm of chromosome 16 at position 11.2.

More precisely, the SRCAP gene is located from base pair 30,699,141 to base pair 30,740,129 on chromosome 16.
