INTRODUCTION: Branchio-oto-renal (BOR) syndrome is an autosomal dominant genetic
disorder characterized by second branchial arch anomalies, hearing impairment,
and renal malformations. Pathogenic mutations have been discovered in several
genes such as EYA1, SIX5, and SIX1. However, nearly half of those affected reveal
no pathogenic variant by traditional genetic testing. METHODS AND MATERIALS:
Whole Exome sequencing and/or Sanger sequencing performed in 10 unrelated
families from Turkey, Iran, Ecuador, and USA with BOR syndrome in this study.
RESULTS: We identified causative DNA variants in six families including novel
c.525delT, c.979T > C, and c.1768delG and a previously reported c.1779A > T
variants in EYA1. Two large heterozygous deletions involving EYA1 were detected
in additional two families. Whole exome sequencing did not reveal a causative
variant in the remaining four families. CONCLUSIONS: A variety of DNA changes
including large deletions underlie BOR syndrome in different populations, which
can be detected with comprehensive genetic testing.
