Molecular Analysis of Down Syndrome 
ately. We are currently analyzing transcribed se- 
quences on distal chromosome 21q (where the 
Down syndrome phenotype maps) and have iso- 
lated multiple candidates. The technique can 
also be applied to determine the timing and tis- 
sues of transcription of likely-to-be-transcribed 
sequences, as determined by other methodolo- 
gies. We will collaborate with researchers per- 
forming these other techniques to make such 
determinations.
