Age at infection with hepatitis B virus (HBV) is a known risk factor for chronic HBV infection. However, in addition, there is some evidence that early age at infection further increases the risk of primary liver cancer beyond its association with increased risk of chronic infection. This systematic...

Facioscapulohumeral muscular dystrophy (FSHD) is the third most diagnosed muscular dystrophy. The disease is caused by genetic and epigenetic disruptions that result in misexpression of the germline transcription factor DUX4 in skeletal muscle, leading to muscle toxicity and turnover. As a gene mise...
