Genotyping the FANCA promoter polymorphism by PCR. Allele 1 amplifies as a band of 151 base pair, allele 2 as a band of 164 base pair. The 3 genotypes are readily distinguishable on a 3 % agarose gel run at 100 V for 1 hour. Homozygous samples for both allele 1 and allele 2 are shown as are heterozygous samples which have both bands.
