PLoS One ; 7 10 : e The lens develops concomitantly with the retina in both human non sex linked disorders worksheet in Richardson zebrafish development. Transgenic fish with the human rhodopsin QX mutation under the control of the zebrafish rhodopsin promoter show photoreceptor degeneration as a consequence of increased apoptotic cell death.
The wild-type retina shows characteristic stratification in three nuclear and two plexiform layers. PAX2 nonsense mutations have been identified in ocular coloboma.
Dis Model Mech ; 4 6 : — Many human genes have been implicated in glaucoma, although the incomplete penetrance reported within families is indicative of a multifactorial aetiology. Because the Y chromosome only experiences recombination with the X non sex linked disorders worksheet in Richardson at the ends as a result of crossing-overthe Y chromosome essentially is reproduced via cloning from one generation to the next.
In women, a recessive allele on one X chromosome is often masked in their phenotype by a dominant normal allele on the other.
The role of the zebrafish nodal-related genes squint and cyclops in patterning of mesendoderm. A SLE association at the Xp The zebrafish eye—a paradigm for investigating human ocular genetics. Am J Hum Genet ; 80 2 : — Close banner Close.
For this reason, and due to its genetic tractability, external fertilisation, and early optical clarity, the zebrafish has become an invaluable vertebrate system to investigate human ocular development and disease. Kristiansen, M. Zebrafish eye development displays in depth molecular complexity and stringent spatiotemporal regulation that incorporates developmental contributions of the surface ectoderm, neuroectoderm and head mesenchyme, similar to that seen in humans.
