SUMMARY: Genetic variants in the SCN1A and PCDH7 genes may influence the risk of epilepsy.
DESCRIPTION: Epilepsy is a condition that causes unpredictable seizures and other health problems. This study looked at patients with general as well as specific types of epilepsy (focal and unclassified) to determine which genetic variants are linked to the disease. After examining 34,853 individuals of European, Asian, or African ancestry, the most significant variants were identified as being located in the SCN1A and PCDH7 genes. SCN1A encodes for a subunit of voltage-dependent sodium channels. These membrane proteins allow sodium to flow into the cell, which is essential for the activity of muscle cells and neurons. The PCDH7 gene encodes a protein that is thought to play a role in cell-cell recognition and adhesion.
