What is the official name of the SGOL1 gene?

The official name of this gene is “shugoshin-like 1 (S. pombe).”

SGOL1 is the gene's official symbol. The SGOL1 gene is also known by other names, listed below.

What is the normal function of the SGOL1 gene?

The SGOL1 gene provides instructions for making part of a protein complex called cohesin. This protein complex helps control the placement of chromosomes during cell division. Before cells divide, they must copy all of their chromosomes. The copied DNA from each chromosome is arranged into two identical structures, called sister chromatids, which are attached to one another during the early stages of cell division. Cohesin holds the sister chromatids together, and in doing so helps maintain the stability of chromosomal structure during cell division.

How are changes in the SGOL1 gene related to health conditions?

chronic atrial and intestinal dysrhythmia - caused by mutations in the SGOL1 gene

At least one SGOL1 gene mutation has been identified in people with chronic atrial and intestinal dysrhythmia (CAID), a disorder affecting the normal rhythmic movements of the heart and the digestive system. The SGOL1 gene mutation that causes CAID replaces a protein building block (amino acid) called lysine with the amino acid glutamic acid at protein position 23, written as Lys23Glu or K23E. Researchers suggest that the mutation may result in a cohesin complex that is less able to hold sister chromatids together, resulting in decreased chromosomal stability during cell division. This instability is thought to cause early aging (senescence) of cells in the intestinal muscle and in the heart's natural pacemaker (the sinoatrial node), resulting in problems maintaining proper rhythmic movements of the heart and intestines and leading to the signs and symptoms of CAID.

It is unclear why SGOL1 gene mutations specifically affect the heart and intestines in CAID. Researchers suggest that the activity (expression) of the SGOL1 gene in certain embryonic tissues or a particular function of the SGOL1 protein in the sinoatrial node and in cells that help control the rhythm of intestinal movements may account for the features of the disorder.

Where is the SGOL1 gene located?

Cytogenetic Location: 3p24.3

Molecular Location on chromosome 3: base pairs 20,159,045 to 20,188,130

The SGOL1 gene is located on the short (p) arm of chromosome 3 at position 24.3.

More precisely, the SGOL1 gene is located from base pair 20,159,045 to base pair 20,188,130 on chromosome 3.
