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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.03524834).

BS1

Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.000177 (27/152304) while in subpopulation EAS AF = 0.00309 (16/5174). AF 95% confidence interval is 0.00194. There are 0 homozygotes in GnomAd4. There are 14 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.Arg462Gln variant in ILDR1 has now been identified by our laboratory in th ree individuals with hearing loss, none of whom had a variant affecting the rema ining copy of the gene. This variant has also been identified in 8/64714 Europea n chromosomes and 6/8534 East Asian chromosomes by the Exome Aggregation Consort ium (ExAC, http://exac.broadinstitute.org; dbSNP rs200630651). Although this var iant has been seen in the general population, its frequency is not high enough t o rule out a pathogenic role. Computational prediction tools and conservation an alyses do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Arg462Gln variant is uncertain. -

Collection Method:clinical testing

The c.1385G>A (p.R462Q) alteration is located in exon 7 (coding exon 7) of the ILDR1 gene. This alteration results from a G to A substitution at nucleotide position 1385, causing the arginine (R) at amino acid position 462 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
