Tetrasomy of the short arm of chromosome 9 constitutes a rare condition resulting in a well clinically recognized syndrome. In our case, in addition to the characteristic phenotype at birth, the existence of a hernia-type Bochdalek diaphragmatic defect was found. Cytogenetic analysis revealed a nonmosaic case of an isochromosome of the entire short arm of chromosome 9 with no involvement of the heterochromatic region of the long arm: 47, XX, +i (9p). Because chromosome 9 contains several gene locus for enzymes and receptors of the retinoid pathway, this case potentially contributes to retinoid hypothesis in the etiology of congenital diaphragmatic hernia.

D065630 Hernias, Diaphragmatic, Congenital Protrusion of abdominal structures into the THORAX as a result of embryologic defects in the DIAPHRAGM often present in the neonatal period. It can be isolated, syndromic, non-syndromic or be a part of chromosome abnormality. Associated pulmonary hypoplasia and PULMONARY HYPERTENSION can further complicate stabilization and surgical intervention.
