Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2 PP3

The NM_001199799.2(ILDR1):​c.80C>A​(p.Thr27Lys) variant causes a missense change. The variant allele was found at a frequency of 0.00000124 in 1,614,046 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T27M) has been classified as Uncertain significance.

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
