Genes affected

CXCR4 (HGNC:2561): (C-X-C motif chemokine receptor 4) This gene encodes a CXC chemokine receptor specific for stromal cell-derived factor-1. The protein has 7 transmembrane regions and is located on the cell surface. It acts with the CD4 protein to support HIV entry into cells and is also highly expressed in breast cancer cells. Mutations in this gene have been associated with WHIM (warts, hypogammaglobulinemia, infections, and myelokathexis) syndrome. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0"). This sequence change replaces serine with glycine at codon 352 of the CXCR4 protein (p.Ser352Gly). The serine residue is highly conserved and there is a small physicochemical difference between serine and glycine. This variant is present in population databases (rs750756138, ExAC 0.006%). This variant has not been reported in the literature in individuals with CXCR4-related conditions. -
