DSCAM and Dscam are both acronyms for Down Syndrome Cell Adhesion Molecule. The case difference is significant: DSCAM refers to the human protein, and Dscam refers to its analog in Drosophila.

Of particular interest is that Dscam has over 38,000 alternative splicing forms from four variable exon clusters. (12, 48, 33 and 2 alternatives respectively.)
