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 significance, criteria provided, single submitterclinical testingGeneDxJun 29, 2020In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; Splice predictors are inconclusive as to whether the variant alters gene splicing. In the absence of RNA/functional studies, the actual effect of this sequence change is unknown.; Has not been previously published as pathogenic or benign to our knowledge -

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2022The c.227C>T (p.A76V) 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 227, causing the alanine (A) at amino acid position 76 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
