Genes affected
CCR3 (HGNC:1604): (C-C motif chemokine receptor 3) The protein encoded by this gene is a receptor for C-C type chemokines. It belongs to family 1 of the G protein-coupled receptors. This receptor binds and responds to a variety of chemokines, including eotaxin (CCL11), eotaxin-3 (CCL26), MCP-3 (CCL7), MCP-4 (CCL13), and RANTES (CCL5). It is highly expressed in eosinophils and basophils, and is also detected in TH1 and TH2 cells, as well as in airway epithelial cells. This receptor may contribute to the accumulation and activation of eosinophils and other inflammatory cells in the allergic airway. It is also known to be an entry co-receptor for HIV-1. This gene and seven other chemokine receptor genes form a chemokine receptor gene cluster on the chromosomal region 3p21. Alternatively spliced transcript variants have been described.

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -12 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.012571186).
BS1
Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.00326 (4760/1461762) while in subpopulation MID AF= 0.018 (104/5768). AF 95% confidence interval is 0.0152. There are 26 homozygotes in gnomad4_exome. There are 2411 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 7 AR gene
