Figure 2. Partial nucleotide sequence of PITX2. A: The sequence in an affected subject shows a heterozygous G>T transversion (indicated by the arrow). The nucleotide substitution at codon 86 results in a change from tryptophan to cysteine. B: Unaffected family members and the general population lack this nucleotide change.
