  • In total we report on mutation analysis of 194 RTS patients; 157 were tested with FISH, 23 with PTT, and 14 with both techniques.

  • 2-150 16 non-microdeletion cases, including 12 from Breuninget al,4 were investigated for only the first 1.2 kb of the CBP transcript by PTT.

  • 2-151 Blough et al found 5/66 microdeletions by FISH; of the remaining 61 cases, 14 were investigated by PTT.
