Mutations in connexin43 (GJA1) perturb bone growth in zebrafish fins.

Abstract excerpt

Mechanisms that regulate the size and shape of bony structures are largely unknown. The molecular identification of the fin length mutant short fin (sof), which causes defects in the length of bony fin ray segments, may provide insights regarding the regulation of bone growth. In this report, we demonstrate that the sof phenotype is caused by mutations in the connexin43 (cx43) gene. This conclusion is supported...
