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]

CEACAM16-AS1 (HGNC:55317): (CEACAM16, CEACAM19 and PVR antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -21 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.94).
• BP6: Variant 19-44703362-T-C is Benign according to our data. Variant chr19-44703362-T-C is described in ClinVar as [Benign]. Clinvar id is 196306.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr19-44703362-T-C is described in Lovd as [Benign].
• BP7: Synonymous conserved (PhyloP=-2.32 with no splicing effect.
• BS1: Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.00114 (173/152222) while in subpopulation SAS AF= 0.0347 (167/4812). AF 95% confidence interval is 0.0304. There are 5 homozygotes in gnomad4. There are 130 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

p.Asn17Asn in exon 3 of CEACAM16: This variant is not expected to have clinical significance because it does not alter an amino acid residue and is not located within the splice consensus sequence. It has been identified in 699/15188 (4.6%) of South Asian chromosomes including 24 homozygotes by the Exome Aggregation Co nsortium (ExAC, http://exac.broadinstitute.org; dbSNP rs202230938). -
