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]

Ile353Met in exon 2 of MARVELD2: This variant is not expected to have clinical s ignificance due to a lack of conservation across species, including mammals. Of note, horse, pika, and tarsier have a methionine (Met) at this position despite high nearby amino acid conservation. In addition, computational analyses (PolyPh en2, SIFT, AlignGVGD) do not suggest a high likelihood of impact to the protein. -
