Genes affected
ILDR1 (HGNC:28741): (immunoglobulin like domain containing receptor 1) This gene encodes a protein that contains an immunoglobulin-like domain. The encoded protein may function as a multimeric receptor at the cell surface. The expression of this gene may be a diagnostic marker for cancer progression. Alternatively spliced transcript variants encoding multiple protein isoforms have been observed for this gene. [provided by RefSeq, Dec 2010]

The p.Leu317Arg variant in ILDR1 has not been previously reported in individuals with hearing loss or in large population studies. Computational prediction tool s and conservation analysis suggest that the p.Leu317Arg variant may impact the protein, though this information is not predictive enough to determine pathogeni city. In summary, the clinical significance of the p.Leu317Arg variant is uncert ain. -
