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.Trp415Cys variant in ILDR1 has not been previously reported in individuals with hearing loss or in large population studies. Computational prediction tool s and conservation analyses suggest that the p.Trp415Cys variant may impact the protein, though this information is not predictive enough to determine pathogeni city. In summary, the clinical significance of the Trp415Cys variant is uncertai n. -
