Genes affected

C5AR1 (HGNC:1338): (complement C5a receptor 1) Enables G protein-coupled receptor activity and complement component C5a receptor activity. Involved in several processes, including complement component C5a signaling pathway; mRNA transcription by RNA polymerase II; and positive regulation of ERK1 and ERK2 cascade. Located in apical part of cell and basolateral plasma membrane. Biomarker of Alzheimer's disease; asthma; chronic obstructive pulmonary disease; rhinitis; and severe acute respiratory syndrome.

The c.316G>A (p.G106R) alteration is located in exon 2 (coding exon 2) of the C5AR1 gene. This alteration results from a G to A substitution at nucleotide position 316, causing the glycine (G) at amino acid position 106 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

The C5AR1 c.316G>A variant is predicted to result in the amino acid substitution p.Gly106Arg. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.020% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/19-47823350-G-A). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
