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 Benign. Variant got -10 ACMG points.

• BP6: Variant 3-121988101-C-CG is Benign according to our data. Variant chr3-121988101-C-CG is described in ClinVar as [Likely_benign]. Clinvar id is 1203287.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00475 (722/152146) while in subpopulation AFR AF= 0.0165 (684/41510). AF 95% confidence interval is 0.0155. There are 8 homozygotes in gnomad4. There are 338 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 8 AR gene
