Hypokalemic Periodic Paralysis Type 2 Due to SCN4A Val1105Met Mutation: A Case Study

Le résumé fourni par la source

Hypokalemic Periodic Paralysis Type 2 (HOKPP2) is a rare autosomal dominant disorder characterized by recurrent episodes of muscle weakness, paralysis, and hypokalemia. In this case report, we present the clinical details of a 49-year-old female diagnosed with HOKPP2. Genetic testing revealed a heterozygous mutation in the Sodium Voltage-Gated Channel Alpha Subunit 4 (SCN4A) gene, confirming the diagnosis of HOKPP2. Management strategies, including potassium supplementation and lifestyle modifications, were implemented, resulting in a significant decrease in the frequency of symptomatic episodes. This case highlights the importance of considering HOKPP2 in patients with recurrent muscle weakness, particularly those with a familial history of similar symptoms. Furthermore, it underscores the crucial role of genetic testing in guiding patient management and facilitating genetic counseling.
