Genes affected

CR2 (HGNC:2336): (complement C3d receptor 2) This gene encodes a membrane protein, which functions as a receptor for Epstein-Barr virus (EBV) binding on B and T lymphocytes. Genetic variations in this gene are associated with susceptibility to systemic lupus erythematosus type 9 (SLEB9). Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Sep 2009]

Computational evidence support a benign effect (BayesDel_noAF=-0.88).

BP6

Variant 1-207471052-T-C is Benign according to our data. Variant chr1-207471052-T-C is described in ClinVar as Likely_benign. ClinVar VariationId is 473094.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=0.766 with no splicing effect.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00107 (163/152232) while in subpopulation NFE AF = 0.0017 (116/68038). AF 95% confidence interval is 0.00145. There are 3 homozygotes in GnomAd4. There are 68 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 3 Unknown,AR,AD gene
