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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 10, 2024The c.523C>T (p.R175W) alteration is located in exon 2 (coding exon 2) of the C5AR1 gene. This alteration results from a C to T substitution at nucleotide position 523, causing the arginine (R) at amino acid position 175 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
