Restriction fragment length polymorphism patterns for IRF6 rs2013162 (A), rs2235375
(B), and rs2235371 (C). (A) Lane M is the
50-bp DNA marker (pUC 19 DNA/MspI), with the arrowhead denoting the
250-bp band. Lanes 1 and 6 represent individuals who are homozygous AA,
3 and 4 represent homozygous CC, and 2 and 5 represent heterozygous CA,
respectively. (B) Lane M is the 50-bp DNA marker, with the arrowhead
denoting the 150-bp band. Lane 1 represents individuals who are
homozygous C, 3 represents homozygous GG, and 2 and 4 represent
heterozygous CG, respectively. (C) Lane M is the 50-bp DNA marker, with
the arrowhead denoting the 250-bp band. Lane 2 represents individuals
who are homozygous TT, 1 and 4 represent homozygous CC, and 3 represents
heterozygous CT, respectively.
