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]

Mar 27, 2023

This variant is present in population databases (rs776953681, gnomAD 0.004%). This sequence change creates a premature translational stop signal (p.Lys87*) in the MARVELD2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in MARVELD2 are known to be pathogenic (PMID: 17186462). This variant has not been reported in the literature in individuals affected with MARVELD2-related conditions. For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 1446607). -
