Genes affected

C1R (HGNC:1246): (complement C1r) This gene encodes a member of the peptidase S1 protein family. The encoded protein is a proteolytic subunit in the complement system C1 complex. The complement system acts as a mediator in the innate immune response by ultimately triggering phagocytosis, inflammation, and rupturing the bacterial cell wall. Mutations in this gene are associated with Ehlers-Danlos Syndrome. [provided by RefSeq, Dec 2018]

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PM1: In a domain CUB 2 (size 112) in uniprot entity C1R_HUMAN there are 13 pathogenic changes around while only 5 benign (72%) in NM_001733.7
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.985
• PP5: Variant 12-7088886-T-C is Pathogenic according to our data. Variant chr12-7088886-T-C is described in ClinVar as [Pathogenic]. Clinvar id is 267356.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr12-7088886-T-C is described in Lovd as [Pathogenic].
