Genes affected

CMKLR1 (HGNC:2121): (chemerin chemokine-like receptor 1) Enables adipokinetic hormone binding activity and adipokinetic hormone receptor activity. Involved in several processes, including negative regulation of NF-kappaB transcription factor activity; positive regulation of macrophage chemotaxis; and regulation of calcium-mediated signaling. Located in plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.605C>T (p.S202L) alteration is located in exon 4 (coding exon 2) of the CMKLR1 gene. This alteration results from a C to T substitution at nucleotide position 605, causing the serine (S) at amino acid position 202 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
