Genes affected
MARVELD2 (HGNC:26401): (MARVEL domain containing 2) The protein encoded by this gene is a membrane protein found at the tight junctions between epithelial cells. The encoded protein helps establish epithelial barriers such as those in the organ of Corti, where these barriers are required for normal hearing. Defects in this gene are a cause of deafness autosomal recessive type 49 (DFNB49). Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2011]

The p.Asp402Asn variant in MARVELD2 has now been identified by our laboratory in three individuals with hearing loss, none of whom had a second variant in the M ARVELD2 gene. It has also been identified in 0.008% (10/129160) of European chro mosomes by gnomAD (http://gnomad.broadinstitute.org). Computational prediction t ools and conservation analysis suggest that the variant may not impact the prote in, though this information is not predictive enough to rule out pathogenicity. In summary, the clinical significance of the p.Asp402Asn variant is uncertain. A CMG/AMP Criteria applied: PM2_Supporting; BP4. -
