Reviewed December 2011

What is the official name of the PRICKLE1 gene?

The official name of this gene is “prickle homolog 1 (Drosophila).”

PRICKLE1 is the gene's official symbol. The PRICKLE1 gene is also known by other names, listed below.

What is the normal function of the PRICKLE1 gene?

The PRICKLE1 gene provides instructions for making a protein called prickle-like 1. The function of this protein is unclear, although it appears to play an important role in the development of the nervous system. Prickle-like 1 is likely part of a chemical signaling pathway known as noncanonical WNT signaling. During development before birth, noncanonical WNT signaling helps to determine the position of various components within cells (cell polarity). This pathway also regulates the movement of nerve cells (neurons) in the developing nervous system.

Studies suggest that prickle-like 1 interacts with other proteins, including RE1-silencing transcription factor (REST). The REST protein regulates several critical genes in neurons by turning off (suppressing) their activity. To regulate these genes, REST must enter the nucleus and attach (bind) to particular regions of DNA. Researchers believe that prickle-like 1 controls REST by transporting it out of the nucleus, which prevents it from binding to DNA and suppressing gene activity. It remains unclear how the interaction between prickle-like 1 and REST contributes to the normal development of the nervous system.

How are changes in the PRICKLE1 gene related to health conditions?

PRICKLE1-related progressive myoclonus epilepsy with ataxia - caused by mutations in the PRICKLE1 gene

At least three mutations in the PRICKLE1 gene have been identified in people with PRICKLE1-related progressive myoclonus epilepsy with ataxia. Each mutation changes a single protein building block (amino acid) in the prickle-like 1 protein. One of the known mutations appears to disrupt the interaction between prickle-like 1 and REST, blocking the transport of REST out of the nucleus. As a result, REST may inappropriately suppress certain genes in the developing nervous system. It is unclear how mutations in the PRICKLE1 gene lead to movement problems, seizures, and the other features of PRICKLE1-related progressive myoclonus epilepsy with ataxia.

Where is the PRICKLE1 gene located?

Cytogenetic Location: 12q12

Molecular Location on chromosome 12: base pairs 42,458,337 to 42,589,769

The PRICKLE1 gene is located on the long (q) arm of chromosome 12 at position 12.
