Atesh, I am not sure how useful it will be to cluster 17 12-variate observations (subjects) using (presumably) Gaussian model-based clustering, but you may look at the following paper: Chen, W.-C. and Maitra, R. (2011). Model-Based Clustering of Regression Time Series Data via APECM – An AECM Algorithm Sung to An Even Faster Beat. Statistical Analysis and Data Mining, 4:567-78. DOI information: 10.1002/sam.10143. There is R code available (not R package), but again, it is not clear to me how useful this is going to be unless there is a structure in the 12 variables you are willing to give in (of course, unless I have misunderstood the context of your question).
