A female infant was admitted to the hospital due to perioral cyanosis two hours after birth. The infant was born at the gestational age of 35 weeks by cesarean section with a birth weight of 2 400 g. Physical examination revealed wry mouth to the left side while crying, small auricles, and high palatal arch; fibrolaryngoscopy suggested bilateral vocal cord paralysis; echocardiography suggested ventricular septal defect; single nucleotide polymorphism testing showed 22q11.21 microdeletion. Therefore, the infant was given a definite diagnosis of asymmetric crying facies syndrome accompanied by 22q11.21 microdeletion. After 8-month follow-up, the infant still had asymmetric crying facies with presence of growth retardation.
