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]

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Feb 14, 2022	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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Possibly 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. ClinVar contains an entry for this variant (Variation ID: 517165). This variant has not been reported in the literature in individuals affected with ILDR1-related conditions. This variant is present in population databases (rs746732835, gnomAD 0.1%). This sequence change replaces serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 387 of the ILDR1 protein (p.Ser387Cys). -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Apr 26, 2022	In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -

p.Ser387Cys in exon 7 of ILDR1: This variant is not expected to have clinical si gnificance due to a lack of conservation across species with several mammals hav ing a cysteine (Cys) at this position. In addition, computational prediction too ls do not suggest a high likelihood of impact to the protein and this variant ha s been identified in 4/11574 Latino chromosomes and 6/66734 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSN P rs746732835). -
