This database was initiated through the efforts of the Retinoschisis Consortium and is currently maintained by Dr J.T. den Dunnen. If you have identified new mutations, please report them as soon as possible.

Curat et al. (2001) have performed functional tests (i.e. in receptor expression, receptor activation and collagen binding) of the mutations Gly70Ser, Arg102Trp, Trp112Cys, Gly140Arg, Gly178Asp, Pro193Leu, Pro203Leu, Arg213Trp and Glu215Gln at the respective positions of the human DDR1 protein. Intracellular retention of mutant retinoschisin for other variants was recently described by Wang et al. 2002.
