Identification of a genetic variant underlying familial cases of recurrent benign paroxysmal positional vertigo.

PLoS One 2021 6;16(5):e0251386. Epub 2021 May 6.

Vestibular Genetics Laboratory, Boys Town National Research Hospital, Omaha, Nebraska, United States of America.

Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo in humans, yet the molecular etiology is currently unknown. Evidence suggests that genetic factors may play an important role in some cases of idiopathic BPPV, particularly in familial cases, but the responsible genetic variants have not been identified. In this study, we performed whole exome sequencing [including untranslated regions (UTRs)] of 12 families and Sanger sequencing of additional 30 families with recurrent BPPV in Caucasians from the United States (US) Midwest region, to identify the genetic variants responsible for heightened susceptibility to BPPV.
