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]

Variant classified as Uncertain Significance - Favor Benign. The Asp487Glu varia nt in MARVELD2 has not been previously reported in individuals with hearing loss and was absent from large population studies. The aspartic acid (Asp) at positi on 487 is not well conserved in mammals or evolutionary distant species, raising the possibility that a change at this position may be tolerated. Of note, the tree shrew and several species of fish carry a glutamic acid (Glu) at this posit ion. Additional computational prediction tools suggest that this variant may not impact the protein, though this information is not predictive enough to rule ou t pathogenicity. In summary, while the clinical significance of the Asp487Glu va riant is uncertain, these data suggest that is more likely to be benign. -
