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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.015267193).
BS1
Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.0000525 (8/152316) while in subpopulation SAS AF = 0.00166 (8/4824). AF 95% confidence interval is 0.000825. There are 0 homozygotes in GnomAd4. There are 6 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAdExome4 at 2 AR gene
