Abstract

Russell-Silver syndrome, also called asymmetric dwarf dysgenesis syndrome is an uncommon genetic disorder presenting with low birth weight, failure to thrive and growth retardation (short stature), developmental delay, facial dysmorphism and hemihypertrophy. The estimated incidence is between 1 case in 3,000 to 1 case in 100,000. We are hereby reporting one such case of postnatal growth retardation with facial dysmorphism and several other features of Russell-Silver syndrome and confirmed by genetic analysis.
