Cohen syndrome is a rare disorder with facial dysmorphism, microcephaly, truncal obesity and intellectual disability. Clinical diagnosis of this syndrome is challenging due to the variability in the phenotype observed in this syndrome. We present a family with two affected siblings with microcephaly and global developmental delay. We report a novel insertion variation in VPS13B gene identified by exome sequencing. This case report expands the mutation spectrum of Cohen syndrome and highlights the utility of next generation sequencing in definitive diagnosis and genetic counseling of such rare disorders.
