Aspa mutations
WebCanavan disease is caused by ASPA mutations that diminish brain aspartoacylase activity, and is characterized by excessive brain storage of the aspartoacylase substrate N-acetyl-L-aspartate (NAA) and by astroglial and intramyelinic vacuolation. Astroglia and arachnoid mater express NaDC3, encoded by … WebIn the ASPA gene of rat (86% identity), however, D249 is conserved whereas D114 is replaced with valine.
