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]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.11629918).

Collection Method: clinical testing

The p.Lys386Asn 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 do not provide strong support for or against an impa ct to the protein. In summary, the clinical significance of the p.Lys386Asn vari ant is uncertain. -
