Abstract

BACKGROUND The pulmonary hypoplasia/agenesis, diaphragmatichernia/eventration, anophthalmia/microphthalmia, and cardiac defect (PDAC) syndrome is a rare medical condition presumably of autosomal recessive way of inheritance with only a few reported cases. Recessive mutations in the STRA6 and both recessive and dominant mutations in RARB gene have been identified as the cause of anophthalmia/microphthalmia and other abnormalities included in the PDAC spectrum. However, those mutations have not been found in all PDAC syndrome cases reviewed from the literature. CASE REPORT We report a case of a full-term living male infant with pulmonary hypoplasia, left diaphragmatic eventration, bilateral microphthalmia, congenitalcardiac defects, and severe pulmonary hypertension. CONCLUSIONS The main feature in the reported cases was anophthalmia/microphthalmia. Therefore, screening for the other associated congenital anomalies is highly suggested. Mutations in STRA6 and RARB genes are commonly encountered in this spectrum. However, whole exome sequencing of suspected cases and their parents is recommended to detect possible de novo mutations. Further reports are needed to identify risk factors and prognosis of this rare syndrome.
