Genes affected

CEACAM16 (HGNC:31948): (CEA cell adhesion molecule 16, tectorial membrane component) The protein encoded by this gene is a secreted glycoprotein that in mouse interacts with tectorial membrane proteins in the inner ear. The encoded adhesion protein is found in cochlear outer hair cells and appears to be important for proper hearing over an extended frequency range. Defects in this gene likely are a cause of non-syndromic autosomal dominant hearing loss. [provided by RefSeq, May 2012]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.Leu39Gln variant in CEACAM16 has not been previously reported in individua ls with hearing loss, but has been identified in 0.08% (20/23988) of African chr omosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitut e.org/; dbSNP rs375722926). Although this variant has been seen in the general p opulation, its frequency is not high enough to rule out a pathogenic role. Compu tational prediction tools and conservation analysis do not provide strong suppor t for or against an impact to the protein. In summary, the clinical significanc e of the p.Leu39Gln variant is uncertain. ACMG/AMP criteria applied: None -
