Definition / general
  • First characterized in 2002 (Hum Mol Genet 2002;11:2979); stem cell marker and oncofetal protein similar to alpha-fetoprotein and glycipan3
  • Zinc-finger transcriptional factor important for embryonic development, at 20q13
Pathophysiology
  • Maintains stem cell identity and governs stem cell self-renewal through transcriptional repression, possibly through repression of different DNA methyltransferases (J Biol Chem 2012;287:1996)
Clinical features
  • SALL4-related disorders include Duane-radial ray syndrome and acro-renal-ocular syndrome (GeneReviews [Internet])
Interpretation
  • Nuclear staining
