SSCP analysis of exon 17 after amplification of genomic DNA with intronic primers. The aberrant bands of patient 3752 (male) were found to have a G to C transition at nucleotide position 1735; patients 4057 (male), 5762(female), and 5587 (female) were found to have a G to A transition at nucleotide position 1735 giving rise to a missense mutation (G579R). The SSCP gels were run with 10% glycerine (see Methods).
