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]

ILDR1 Gene-Disease associations (from GenCC):

• autosomal recessive nonsyndromic hearing loss 42

  Inheritance: AR Classification: DEFINITIVE, STRONG Submitted by: Labcorp Genetics (formerly Invitae), G2P, PanelApp Australia
