THE GENETIC BASIS OF HUMAN BIRTH ABNORMALITIES AND DEGENERATIVE DISEASE
STEM CELL BIOLOGY IN HUMAN DEVELOPMENT AND DISEASE
We study the genetic basis of normal embryonic development (mostly eyes and limbs) and the processes that can go wrong in humans. We also study stem cell activity in adults, focusing on degenerative disease and fertility problems.
1) The development and evolution of eyes. There are several projects on the go.
a) The roles of a transcription factor, Pax6, in eye development and disease .We examine how mutations in Pax6 change the cell surface properties of mutant cells, and how this may impact on the eye.
Patients with mutations in the PAX6 gene develop multiple eye abnormalities, including any or all of: aniridia (absence of iris), corneal opacity (aniridia-related keratopathy), cataract (lens clouding), glaucoma and long-term retinal degeneration. We are interested in developing new therapeutic strategies

b) The development of eyes in true moles (Talpa). Moles live most of their lives underground and over evolutionary time we expect their eyes to degenerate. We study the Iberian Mole Talpa occidentalis, in which the eyes are permanently closed, and determine how the genetic pathways that underlie eye development are breaking down in this species.

2) The genetic control of axon guidance and epithelial cell migration. What pushes a cell or a growth cone from point A to point B? We examine the relative contribution of chemical and contact mediated guidance cues in vivo.

3) The genetics and etiology of Congenital Talipes Equinovarus (clubfoot)
We study the genetic and environmental factors that underlie clubfoot - an extremely common birth abnormality (1 in 500 babies) for which virtually nothing is clear about the causes.
