Genes affected
C3AR1 (HGNC:1319): (complement C3a receptor 1) C3a is an anaphylatoxin released during activation of the complement system. The protein encoded by this gene is an orphan G protein-coupled receptor for C3a. Binding of C3a by the encoded receptor activates chemotaxis, granule enzyme release, superoxide anion production, and bacterial opsonization. [provided by RefSeq, May 2016]

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 08, 2022 | The c.549T>G (p.D183E) alteration is located in exon 2 (coding exon 1) of the C3AR1 gene. This alteration results from a T to G substitution at nucleotide position 549, causing the aspartic acid (D) at amino acid position 183 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
