Cornelia de Lange syndrome is a genetic disorder with multiple system abnormalities. It is especially characterized by typical facial appearance and hirsutism. Growth and mental retardation, gastrointestinal, cardiovascular, and orthopedic abnormalities are other important features of this syndrome. In this case, we present a rare manifestation of Cornelia de Lange syndrome with a unilateral pes equinovarus deformity without other more specific orthopedic manifestations. Ponseti method's was applied as the initial procedure. Afterwards, complete subtalar release was performed. After four years follow-up, clinical and radiological results were satisfactory. Unilateral pes equinovarus deformity may be a part of this syndrome as well as a sporadic presentation. The discrimination is important for anesthetic procedures and surgical outcomes.
