Key result
Voltage-gated potassium channel polymorphisms in KCNAB1 and KCNJ10 were significantly correlated with the risk of epilepsy in the Saudi population (p=0.04 for KCNAB1 variants).
Why the study?
Genetics plays a fundamental role in the development and progression of epilepsy, but the influence of voltage-gated K+ channels on epilepsy risk required investigation.
Are voltage-gated potassium channel polymorphisms associated with the risk of epilepsy in the Saudi population?

Are voltage-gated potassium channel polymorphisms associated with the risk of epilepsy in the Saudi population?
Specific voltage-gated potassium channel polymorphisms in KCNAB1 and KCNJ10 are associated with an increased risk of epilepsy in the Saudi population.
Hypothesis-generating for epilepsy genetics in Saudis; leaves open replication before any clinical application.
Background and Objectives: Epilepsy, known as an unprovoked seizure, arises from the human brain. Genetics plays a fundamental role in the development and progression of the disorder. This study aimed to investigate the influence of voltage-gated K+ channels on the risk of epilepsy. Materials and Methods: Several genetic variants were examined using PCR sequencing. This case–control study was conducted on 296 individuals who were diagnosed with epilepsy, in addition to 293 healthy participants. Results: This study revealed that within KCNAB1, both rs3755631 and rs4679773 are correlated with epilepsy, and the p-values = 0.04 for both allelic associations. In addition, regarding the KCNJ10 gene, we found that rs2820585, rs946420, rs1186679, rs61822012, and rs1186685 were significantly correlated with epilepsy risk (p-values = 0.034, 0.045, 0.021, 0.048, and 0.018), respectively. Conclusions: From the current study, we conclude that voltage-gated potassium channels can impact epilepsy risk and can also interfere with the prognosis of epilepsy.

Alghamdi et al. (2025) conducted a case-control in Epilepsy (n=589). Voltage-gated potassium channel polymorphisms vs. Healthy participants was evaluated on Risk of epilepsy (p=0.04). Voltage-gated potassium channel polymorphisms in KCNAB1 and KCNJ10 were significantly correlated with the risk of epilepsy in the Saudi population (p=0.04 for KCNAB1 variants).
