Genes affected

CD83 (HGNC:1703): (CD83 molecule) The protein encoded by this gene is a single-pass type I membrane protein and member of the immunoglobulin superfamily of receptors. The encoded protein may be involved in the regulation of antigen presentation. A soluble form of this protein can bind to dendritic cells and inhibit their maturation. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0015002787).
• BP6: Variant 6-14135163-G-A is Benign according to our data. Variant chr6-14135163-G-A is described in ClinVar as [Benign]. Clinvar id is 782470.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0135 (2056/152264) while in subpopulation AFR AF= 0.0472 (1962/41542). AF 95% confidence interval is 0.0455. There are 48 homozygotes in gnomad4. There are 985 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 48 AR gene
