The etiology of congenital diaphragmatic hernia (CDH) is unclear and its pathogenesis is controversial. Because previous reports have inconsistently noted the type and frequency of malformations associated with CDH, we assessed these associated malformations ascertained between 1979 and 2003 in 334,262 consecutive births. Of the 115 patients with the most common type of CDH, the posterolateral, or Bochdalek-type hernia, 70 (60.8%) had associated malformations. These included: chromosomal abnormalities (n = 21, 30.0%); non-chromosomal syndromes (Fryns syndrome, fetal alcohol syndrome, De Lange syndrome, CHARGE syndrome, Fraser syndrome, Goldenhar syndrome, Smith-Lemli-Opitz syndrome, multiple pterygium syndrome, Noonan syndrome, and spondylocostal dysostosis); malformation sequences (laterality sequence, ectopia cordis); malformation complexes (limb body wall complex) and non syndromic multiple congenital anomalies (MCA) (n = 30, 42.9%). Malformations of the cardiovascular system (n = 42, 27.5%), urogenital system (n = 27, 17.7%), musculoskeletal system (n = 24, 15.7%), and central nervous system (n = 15, 9.8%) were the most common other congenital malformations. We observed specific patterns of malformations associated with CDH which emphasizes the need to evaluate all patients with CDH for possible associated malformations. Geneticists and pediatricians should be aware that the malformations associated with CDH can often be classified into a recognizable malformation syndrome or pattern (57.1%).

The availability of microarray technology has led to the recent recognition of copy number abnormalities of distal chromosome 22q11.2 that are distinct from the better-characterized deletions and duplications of the proximal region. This report describes five unrelated individuals with copy number abnormalities affecting distal chromosome 22q11.2. We report on novel phenotypic features including diaphragmatic hernia and uterine didelphys associated with the distal microdeletion syndrome; and frontomedial polymicrogyria and callosal agenesis associated with the distal microduplication syndrome. We describe the third distal chromosome 22q11.2 microdeletion patient with Goldenhar syndrome. Patients with distal chromosome 22q11.2 copy number abnormalities exhibit inter- and intra-familial phenotypic variability, and challenge our ability to draw meaningful genotype-phenotype correlations.

Oculo-auriculo-vertebral (OAV) spectrum summarizes a continuum of ocular, auricular, and vertebral anomalies. Goldenhar syndrome is a variant of this spectrum and is characterized by pre-auricular skin tags, microtia, facial asymmetry, ocular abnormalities, and vertebral anomalies of different sizes and shapes. Most cases are thought to be sporadic. However, a few families were reported to have an autosomal recessive inheritance and other families' presentation of the syndrome strongly supported an autosomal dominant inheritance. We report OAV in a female infant presenting with tracheomalacia, diaphragmatic hernia, encephalomeningocele, sacral neural tube defect, and cardiac defect and her brother having no more than dysmorphic features. The mode of inheritance in this family supports an autosomal recessive inheritance where the transmission was from normal first-degree consanguineous parents to one of the sons and to the daughter. This report further broadens the clinical presentation and symptoms of OAV and supports the hypothesis advancing OAV as a genetically heterogeneous disorder.
