Craniofacial, skeletal, and cardiac defects associated with altered embryonic murine Zic3 expression following targeted insertion of a PGK-NEO cassette.

Abstract excerpt

Mutation in ZIC3 (OMIM #306955), a zinc finger transcription factor, causes heterotaxy (situs ambiguus) or isolated congenital heart defects in humans. Mice bearing a null mutation in Zic3 have left-right patterning defects with associated cardiovascular, vertebra/rib, and central nervous system malformations. Although XZic3 is thought to play a critical role in Xenopus neural crest development, no defects in...
