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]

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.Thr27Met variant in ILDR1 has not been previously reported in individuals with hearing loss, but has been identified in 3/66724 of European chromosomes an d 1/8654 of East Asian chromosomes by the Exome Aggregation Consortium (ExAC, ht tp://exac.broadinstitute.org; dbSNP rs145984650). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Computational prediction tools and conservation analyses do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Thr27Met variant is uncertain. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.80C>T (p.T27M) alteration is located in exon 2 (coding exon 2) of the ILDR1 gene. This alteration results from a C to T substitution at nucleotide position 80, causing the threonine (T) at amino acid position 27 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
