Diverse spectrum of rare deafness genes underlies early-childhood hearing loss in Japanese patients: a cross-sectional, multi-center next-generation sequencing study.
Taken together, our experiments demonstrate that the SIX1BOR mutations contribute to the pathology of the disease through at least two different mechanisms that involve: 1) abolishing the formation of the SIX1-EYA complex or 2) diminishing the ability of SIX1 to bind DNA.
The current screen of 247 BOR families detected five novel SIX1 mutations (c.50T>A, c.218A>C, c.317T>G, c.329G>A, c.334C>T) and one previously reported mutation (c.328C>T) seen in 5 unrelated families.
We examined six Danish families with BOR syndrome by assessing linkage to BOR loci, by performing EYA1 multiplex ligation-dependent probe amplification (MLPA) analysis for deletions and duplications and by sequencing of EYA1, SIX1 and SIX5.
