We report a male infant with partial DiGeorge syndrome characterized by truncus arteriosus, typical facial dysmorphism, hypocalcemia, lymphocytopenia with T-cell deficiency, and chromosome 22q11.2 deletion. Transient lymphocytopenia was noted for 5 days after birth and hypocalcemia was corrected with calcium gluconate administration. Surgical. correction of the truncus arteriosus was performed at the age of 3 months. Unfortunately, the patient subsequently had an unwitnessed cardiac arrest, and despite resuscitation, died at the age of 4 months.[SDGs]SDG3gluconate calcium; parathyroid hormone; article; case report; chromosome 22q; chromosome deletion; computer assisted tomography; cyanosis; DiGeorge syndrome; echocardiography; face dysmorphia; fluorescence in situ hybridization; heart arrest; heart murmur; human; hypocalcemia; hypoparathyroidism; infant; lymphocytopenia; male; patent ductus arteriosus; resuscitation; T lymphocyte; thymus disease; Chromosome Deletion; Chromosomes, Human, Pair 22; DiGeorge Syndrome; Fatal Outcome; Heart Arrest; Humans; In Situ Hybridization, Fluorescence; Infant, Low Birth Weight; Infant, Newborn; Male; Truncus Arteriosus, Persistentjournal article154937392-s2.0-4644254303
