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

This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 151 of the ILDR1 protein (p.Gly151Arg). This variant is present in population databases (rs727503098, gnomAD 0.08%). This variant has not been reported in the literature in individuals affected with ILDR1-related conditions. ClinVar contains an entry for this variant (Variation ID: 163701). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

The p.Gly151Arg 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.Gly151Arg variant may impact the protein, though this information is not predictive enough to determine pathogeni city. In summary, the clinical significance of the p.Gly151Arg variant is uncert ain. -

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

The c.451G>A (p.G151R) alteration is located in exon 4 (coding exon 4) of the ILDR1 gene. This alteration results from a G to A substitution at nucleotide position 451, causing the glycine (G) at amino acid position 151 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
