Genes affected
CXCR2 (HGNC:6027): (C-X-C motif chemokine receptor 2) The protein encoded by this gene is a member of the G-protein-coupled receptor family. This protein is a receptor for interleukin 8 (IL8). It binds to IL8 with high affinity, and transduces the signal through a G-protein activated second messenger system. This receptor also binds to chemokine (C-X-C motif) ligand 1 (CXCL1/MGSA), a protein with melanoma growth stimulating activity, and has been shown to be a major component required for serum-dependent melanoma cell growth. This receptor mediates neutrophil migration to sites of inflammation. The angiogenic effects of IL8 in intestinal microvascular endothelial cells are found to be mediated by this receptor. Knockout studies in mice suggested that this receptor controls the positioning of oligodendrocyte precursors in developing spinal cord by arresting their migration. This gene, IL8RA, a gene encoding another high affinity IL8 receptor, as well as IL8RBP, a pseudogene of IL8RB, form a gene cluster in a region mapped to chromosome 2q33-q36. Alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Nov 2009]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -12 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.86).
BS1
Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.0246 (3743/152010) while in subpopulation SAS AF= 0.0479 (230/4798). AF 95% confidence interval is 0.0429. There are 56 homozygotes in gnomad4. There are 1878 alleles in male gnomad4 subpopulation. Median coverage is 30. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 56 gene
