Knock-in of alpha3 connexin prevents severe cataracts caused by an alpha8 point mutation.

Abstract excerpt

A G22R point mutation in alpha8 connexin (Cx50) has been previously shown to cause a severe cataract by interacting with endogenous wild-type alpha3 connexin (Cx46) in mouse lenses. Here, we tested whether a knocked-in alpha3 connexin expressed on the locus of the endogenous alpha8 connexin could modulate the severe cataract caused by the alpha8-G22R mutation. We found that the alpha3(-/-) alpha8(G22R/-) mice...
