    Abstract:

    AIM: To study clinical features and gene mutations within the paired-like homeodomain transcription factor 2 (PITX2) gene in a pedigree of bilateral limbal dermoids.METHODS: Complete eye examinations have been performed on each individual of the family. Exons of paired-like homeodomain transcription factor 2 (PITX2) were amplified by polymerase chain reaction, sequenced, and compared with a reference database.RESULTS: We described the phenotype, clinic findings in a family with two affected members. The masses of the proband’s eyes were excised surgically demonstrating a dermoid cyst by histopathological examination. No mutation was detected in the gene PITX2 in this pedigree.CONCLUSION: A family of limbal dermoid cyst was reported.In addition, no pathogenic sequence variations were found in PITX2, indicating that this phenotype in this family is a distinctive entity.
