Abstract

BACKGROUND: This retrospective study assesses the contribution of genetic disorders in fetuses undergoing postmortem evaluation and the performance of a clinical dysmorphology based systematic approach toward genetic diagnosis. MATERIALS AND METHODS: Ninety fetuses, including spontaneous losses and terminated pregnancies, underwent a postmortem evaluation including dysmorphological examination, radiological studies, and histopathological examination. Genetic testing including karyotyping, biochemical testing, Sanger sequencing, and exome sequencing were performed selectively. RESULTS: A genetic etiology was concluded in 48 fetuses (55%). As a standalone test, dysmorphological examination was able to ascertain a definite genetic diagnosis in sixteen cases, histopathology in six; and karyotyping, biochemical testing and exome sequencing in two cases each (Total 28). Additionally, dysmorphology findings indicated possible genetic disorder in 20 cases. CONCLUSION: Genetic etiologies contribute significantly to fetuses undergoing autopsy in this series. A systematic approach to postmortem fetal evaluation guided by dysmorphological examination provides high diagnostic yield toward perinatal genetic diagnosis.
