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]

Variant classified as Uncertain Significance - Favor Benign. The p.Phe310Cys var iant in ILDR1 has not been previously reported in individuals with hearing loss, but has been identified in 0.17% (17/10148) of Ashkenazi Jewish chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs199882599). Although this variant has been seen in the general population, it s frequency is not high enough to rule out a pathogenic role. Computational pre diction tools and conservation analyses suggest that this variant may not impact the protein, though this information is not predictive enough to rule out patho genicity. In summary, while the clinical significance of this variant is uncerta in, these data suggest that it is more likely to be benign. -

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

The c.929T>G (p.F310C) alteration is located in exon 7 (coding exon 7) of the ILDR1 gene. This alteration results from a T to G substitution at nucleotide position 929, causing the phenylalanine (F) at amino acid position 310 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
