Genes affected

SERPING1 (HGNC:1228): (serpin family G member 1) This gene encodes a highly glycosylated plasma protein involved in the regulation of the complement cascade. Its encoded protein, C1 inhibitor, inhibits activated C1r and C1s of the first complement component and thus regulates complement activation. It is synthesized in the liver, and its deficiency is associated with hereditary angioneurotic oedema (HANE). Alternative splicing results in multiple transcript variants encoding the same isoform.

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.98).
• BP6: Variant 11-57610852-C-T is Benign according to our data. Variant chr11-57610852-C-T is described in ClinVar as [Benign]. Clinvar id is 983234.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr11-57610852-C-T is described in Lovd as [Benign].
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.415 is higher than 0.05.

-

This variant is considered likely benign or benign based on one or more of the following criteria: allele frequency is >5% in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium (BA1), allele frequency is greater than expected for disorder (BS1), it is observed in a healthy adult individual (BS2), it is predicted to be benign by multiple in silico algorithms (BP4), it is found in a case with an alternate molecular basis for the disease (BP5) and/or reputable source recently reports variant as benign (BP6). -
