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]

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 532 of the ILDR1 protein (p.Arg532Cys). This variant is present in population databases (rs201511787, gnomAD 0.01%). 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: 1315006). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0". The cysteine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1594C>T (p.R532C) alteration is located in exon 7 (coding exon 7) of the ILDR1 gene. This alteration results from a C to T substitution at nucleotide position 1594, causing the arginine (R) at amino acid position 532 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
