I have done 300K SNP array by Illumina for 27 patients and found a common deletions in 9 of them. Now I would like to study shared haplotype in this specific region in these 9 patients. How do I do it in easier way? Which program is better and how can I do it? I tried shared haplotype by plink but it is base on case-control and I am working on family-based study.Thanks
