Three novel PAX6 mutations in patients with aniridia

Abstract

Aims: To describe mutations in the PAX6 gene in five patients with aniridia from three unrelated families.

Methods: The PAX6 gene was analysed using single stranded conformational polymorphism analysis and direct sequencing.

Results: In one family, three individuals from two generations had aniridia, whereas in each of the other families only one member was affected. The first patient had the heterozygous Q221X (1023C → T) nonsense mutation in exon 8. The same mutation was found in his mother and sister. Another patient had a heterozygous Q297X (1252C → T) mutation in exon 10. The third patient carried a heterozygous IVS5+2T → C mutation leading to aberrant splicing of mRNA.

Conclusions: These findings provide further examples of haploinsufficiency of PAX6 in aniridia.

  • aniridia
  • PAX6 mutations
  • eye malformations
  • PCR, polymerase chain reaction
  • SSCP, single stranded conformational polymorphism
  • WAGR, Wilms’s tumour, aniridia, genitourinary abnormalities, and mental retardation
