Genes affected
OTOL1 (HGNC:34071): (otolin 1) This gene encodes a secreted glycoprotein with a C-terminal complement Cq1-like globular domain that belongs to the C1q/tumor necrosis factor-related protein (CTRP) family. The encoded protein is expressed in the inner ear and forms a multimeric complex called the otoconia, together with cerebellin-1 and otoconin-90, as part of the otoconial membrane. It contains extensive posttranslational modifications including hydroxylated prolines and glycosylated lysines. Naturally occurring mutations in this gene are associated with abnormal otoconia formation and balance deficits resulting from vestibular dysfunction. [provided by RefSeq, Jul 2017]

not specified Benign:1
Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsApr 26, 2023This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
