Together, these data suggest that SLC26A4, FOXI1 and KCNJ10 are not major determinants in unilateral deafness and enlarged vestibular aqueduct compared with their implication in Pendred syndrome and non-syndromic bilateral enlarged vestibular aqueduct.
We also used this approach to scan for mutations in KCNJ10 and FOXI1, two genes reported to play a role in the pathogenesis of Pendred syndrome and enlarged vestibular aqueduct.
