(The eye anomaly «merle» can be confused
with choroidal hypoplasia, primarily in dogs from merle to merle breeding and whose coat color is whiter than their littermates.
The result is the percentage of collies affected
with choroidal hypoplasia remains high, but the severe grades of the disease (colobomas and retinal detachments) have decreased due to this conscientious breeding.
Specifically, the team hypothesizes that microRNA miR - 24 is a key regulator of actin cytoskeleton dynamics (i.e. the inner structural support of a cell); therefore, it plays a critical role in regulating multiple disease processes, including the angiogenesis (blood vessel growth), inflammation, and fibrosis (thickening and scarring of tissue) associated
with choroidal neovascularization (CNV) in wet AMD.

Our objective is to determine whether this mutation is involved in AMD by (1) understanding the functional consequences of this genomic variation on expression of COL8A1 and / or its neighbor genes, and (2) investigating photoreceptors and RPE cell survival, retinal and
