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 Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.54).
• BP6: Variant 3-121994198-G-A is Benign according to our data. Variant chr3-121994198-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 44144.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr3-121994198-G-A is described in Lovd as [Likely_benign].
