Seaver Cassidy syndrome is a very rare disorder characterized by certain facial, genital, and skeletal deformities, as well as an unusual susceptibility to bleeding.[1] Seaver Cassidy syndrome was first described in 1991 by Laurie Seaver and Suzanne Cassidy.[2]


Signs of Seaver Cassidy syndrome include several facial disorders, including hypertelorism and telecanthus, epicanthal folds, downslanting palpebral fissures, ptosis, a broad nasal bridge, malar hypoplasia, a thin upper lip, a smooth philtrum, and low-set, prominent ears. Males with Seaver Cassidy syndrome may also experience an underdeveloped shawl scrotum and cryptorchidism. Skeletal anomalies, such genu valgum, hyperextended joints, or cubitus valgus, may also be present.[2]
