Patient 1 was only diagnosed with Epstein syndrome at the age of thirty-three where the mutation in the nonmuscle myosin was noticed. His eldest son also carried the same mutation.An Epstein syndrome patient with oral lesions was recorded to be the first with this symptom. The patient was a twenty-six-year-old female who was diagnosed with thrombocytopaenia with purpura at age four. She was then finally diagnosed with Epstein syndrome at twenty-two years old when she developed symptoms for hearing loss as well as proteinuria and hematuria revealing poor kidney function. After an oral examination, palatal purpua in her mouth was observed.A Japanese male was diagnosed with sporadic Epstein syndrome where both his parents did not have the R702H mutation. He was initially diagnosed with chronic macrothrombocytopaenia at three years old and throughout childhood symptoms for hearing loss and proteinuria were observed. At 24 years old his kidney failure had severely progressed as well as his hearing loss and thrombocytopenia. A genetic test confirmed he had the R702H mutation despite having no familial record of Epstein syndrome. References
