The first case of Silver-Russell syndrome accompanied by linea alba hernia in China

A 10-month-old Chinese boy presented with delayed motor development for seven months. Blood and biochemistry investigations revealed no abnormalities. The physical examination showed poor postnatal growth (below -2 standard deviation from the mean at diagnosis), preservation of the occipitofrontal head circumference with delayed closure of the anterior fontanel, a classical triangular facial phenotype, asymmetry of the lower extremities and other characteristic features that fulfil the diagnostic criteria of Silver-Russell syndrome clinically. As PubMed and web searches revealed no similar findings, we believe that this may be the first case of Silver-Russell syndrome with linea alba hernia and pes varus reported in China, and possibly the world. The genetic deficit responsible for this case is still under investigation.
