Abstract

Abstract Background Cornelia de Lange syndrome is a relatively uncommon disorder associated with multiple congenital anomalies/mental retardation of unknown etiology with its incidence varying from 1:10,000 to 1:50,000 live births in different population groups without any known racial predilections. Main clinical features of this syndrome consist of distinctive dysmorphic facial appearance, growth retardation, developmental delay, mental retardation, hirsutism, and skeletal formation anomaly. Case presentation This case presents a variation of unknown significance in the NIPBL gene-exon 39, chr5:37048649T>A c.6635T>A (p.Val2212Glu) with clinical phenotype of Cornelia de Lange syndrome. Our patient belonged to South Indian origin with clinical features of synophrys, micrognathia, long smooth philtrum, and clinodactyly with bilateral simian crease. Conclusion Cornelia de Lange syndrome is a rare but well-characterized disorder, in which multiple systems of the body are affected. It is important that the treating physician ensures coordination of the diversiform aspects of care in both childhood and adulthood. Proper and timely diagnosis using next generation sequencing helps in management and possibility of prenatal diagnosis.
