Genes affected

ACKR4 (HGNC:1611): (atypical chemokine receptor 4) The protein encoded by this gene is a member of the G protein-coupled receptor family, and is a receptor for C-C type chemokines. This receptor has been shown to bind dendritic cell- and T cell-activated chemokines including CCL19/ELC, CCL21/SLC, and CCL25/TECK. A pseudogene of this gene is found on chromosome 6. Alternatively spliced transcript variants encoding the same protein have been described. [provided by RefSeq, Jul 2013]

ACKR4 links:

ACAD11 (HGNC:30211): (acyl-CoA dehydrogenase family member 11) This gene encodes an acyl-CoA dehydrogenase enzyme with a preference for carbon chain lengths between 20 and 26. Naturally occurring read-through transcription occurs between the upstream gene NPHP3 (nephronophthisis 3 (adolescent)) and this gene. [provided by RefSeq, Aug 2015]

Ambry Genetics

Jul 06, 2021

The c.889T>C (p.C297R) alteration is located in exon 1 (coding exon 1) of the ACKR4 gene. This alteration results from a T to C substitution at nucleotide position 889, causing the cysteine (C) at amino acid position 297 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
