Detection of the mosaic c.2700_2701delTC mutation in patient C107. Nucleotide 2700 is indicated with an arrow. (A) The aberrant bands indicated by the bracket were excised from the SSCP/HD gel. The resulting DNA sequence is shown to the right. (B) DNA sequence from DNA extracted from tumor-derived cells from the patient. (C) The DNA sequence from DNA isolated from the patient's blood lymphocytes.
