Peters anomaly and Axenfeld–Rieger syndrome (ARS) belong to the overlapping spectrum of disorders summarized as anterior segment dysgenesis (ASD). Five patients from a family with Peters’ anomaly and ARS were screened for mutations in the PITX2, CYP1B1 and FOXC1 genes by direct sequencing. All affected family members examined were heterozygous for a single nucleotide substitution, resulting in a nonsense mutation (Q120X) at a highly conserved residue of the FOXC1 gene that is essential for DNA binding. In this pedigree, all affected family members were diagnosed with ARS except for one who shows bilateral Peters’ anomaly. Our findings support the role of FOXC1 mutations in the spectrum of ASD.
