Fig. 3From: Detection of a heterozygous germline APC mutation in a three-generation family with familial adenomatous polyposis using targeted massive parallel sequencing in VietnamValidation of the deletion in affected members using Sanger sequencing. (Top) The heterozygous deletion c.3927_3931delAAAGA in proband II-2: the deletion causes a frameshift and creates a Stop codon downstream. (Bottom) The complete sequence in unaffected members.
