Leucine Rich, Glioma Inactivated 1 (LGI1)

LGI1  contains a hydrophobic segment representing a putative transmembrane domain with the amino terminus located outside the cell. It also contains leucine-rich repeats with conserved cysteine-rich flanking sequences. This gene is predominantly expressed in neural tissues and its expression is reduced in low grade brain tumors and significantly reduced or absent in malignant gliomas.LGI1 gene has been implicated in the control of cancer metastasis and in a predisposition to epilepsy. Following genetic linkage studies placing the hereditary form of autosomal dominant partial epilepsy with Auditory features (ADPEAF) on chromosome region 10q24 mutation analysis of affected members in these families demonstrated LGI1 was the cause of the disease.
