The abnormality of the <jats:italic>MYH9<\/jats:italic> gene has a strong relationship to the severity of the disease. Severe Epstein syndrome progresses to end\u2010stage renal disease rapidly after adolescence. There is no established therapy.

Despite treatment with renin\u2013angiotensin system blockers, nephropathy was refractory and progressed rapidly, and the patients required dialysis or renal transplantation after adolescence. Early preparation for treatment based on early and accurate diagnosis of Epstein syndrome enabled two patients to undergo pre\u2010emptive renal transplantation. For these patients, we kept the platelet count above 100 \u00d7 10<jats:sup>9<\/jats:sup>\/L until day 7 after renal transplantation with platelet transfusions for macrothrombocytopaenia, and no postoperative bleeding episodes occurred.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Epstein syndrome nephropathy due to a severe <jats:italic>MYH9<\/jats:italic> gene mutation can be refractory and progress rapidly; therefore, early and accurate diagnosis is important for safer therapeutic options including pre\u2010emptive renal transplantation. By keeping the platelet count above 100 \u00d7 10<jats:sup>9<\/jats:sup>\/L during the perioperative period, renal transplantation can be a safe treatment option for severe Epstein syndrome
