septin


Also found in: Wikipedia.

septin

A protein encoded on chromosome 16p11.1 that belongs to the septin family of GTPases, which are required for cytokinesis and maintaining cell morphology.

Molecular pathology
Septin 1 forms homo- and heterooligomeric filaments and may contribute to the neurofibrillary tangles in Alzheimer's disease.

The first blood test to be commercialized for CRC screening (methylated septin 9 [Epi pro-Colon], Epigenomics, San Diego, California) has such suboptimal performance characteristics that the USPSTF did not include it among its recommended tests, (1) and the USMSTF on CRC flatly recommended against its use.

Mt-sDNA had high sensitivity, similar specificity, and high costs compared with those of FIT alone.[12] In 2016, the first blood-based test, i.e., mSEPT9 assay was evolved, as hypermethylated DNA of septin 9 gene might be shed into the bloodstream from CRC tissues and be detected.
