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]

Variant classified as Uncertain Significance - Favor Benign. The p.Glu454Lys var iant in ILDR has now been identified by our laboratory in two individuals with h earing loss, but a variant affecting the remaining copy of ILDR1 was not identif ied in either one. This variant has been identified in 2/64670 European chromoso mes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; d bSNP rs727503097); however, this frequency is not high enough to rule out a path ogenic role. The glutamic acid (Glu) at position 454 is not conserved in mammals or evolutionary distant species, raising the possibility that a change at this position may be tolerated. Additional computational prediction tools suggest tha t this variant may not impact the protein, though this information is not predic tive enough to rule out pathogenicity. In summary, while the clinical significan ce of the p.Glu454Lys variant is uncertain, available data suggest that it is mo re likely to be benign. -
