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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineSep 04, 2017Variant classified as Uncertain Significance - Favor Benign. The c.*2G>A variant in MARVELD2 has not been previously reported in individuals or any other famili es with non-syndromic hearing loss. This variant has been identified in 1/33384 Latino chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.bro adinstitute.org; dbSNP rs530892254). This variant is located in the 3' UTR, and it is unknown whether this variant could impact the protein. Of note, an adenin e (A) nucleotide is present in 9 mammals. In summary, while the clinical signifi cance of the c.*2G>A variant is uncertain, these data suggest that it is more li kely to be benign. -
