Abstract

We describe a patient with multiple congenital anomalies, including hemifacial microsomia, asymmetric macrostomia, dysplastic mandible, multiple preauricular tags, atresia of the external auricular canal, and vertebral anomalies, which coincide with oculo-auriculo-vertebral spectrum. G-banding (∼850 band level) showed a normal 46, XY karyotype. A genome-wide screen for copy number variations (CNVs) using single nucleotide polymorphism (SNP) arrays revealed a 1 Mb and a 167 kb deletion both on chromosome 5q13.2, which were absent in the parents and in 27 controls. Sixteen genes were located in the deleted region, including BIR1C and OCLN, which are involved in apoptosis. Haploinsufficiency of these genes may be contributing to the phenotype in this patient. To our knowledge, there are no previous reports of this 5q13.2 deletion in a patient with oculo-auriculo-vertebral spectrum.
