Abstract

Emanuel syndrome (ES) is the most frequent type of recurrent non‑Robertsonian translocation that is characterized by numerous anomalies. Over 100 patients with ES have been described in the literature. The phenotype of this syndrome varies but often consists of facial dysmorphism, microcephaly, severe intellectual disability, developmental retardation, congenital heart disease and genital anomalies. The present study describes a 2‑year‑old boy with multiple malformations, including facial dysmorphism, severe intellectual disability, growth retardation, congenital heart disease, cleft lip and palate, genital malformation (micropenis), amblyopia, thymic dysplasia and hearing impairment. The karyotype of the patient was 47,XY,+del(22)(q13), and the maternal karyotype was 46,XX,t(11;22)(q25;q13),9qh‑,15p+. Single‑nucleotide polymorphism‑array analysis of the proband indicated a partial duplication of chromosomes 22 and 11 at 22q11.1‑q11.21 and 11q23.3‑q25, respectively, which confirmed the diagnosis of ES. To date, no cases of ES have been reported in mainland China. The present case further emphasizes the necessity and importance of high‑resolution techniques for genetic diagnosis and for subsequent genetic counseling. The present study contributed to the phenotypic delineation of ES and confirmed the first ES patient in mainland China.
