Genes affected

FCN2 (HGNC:3624): (ficolin 2) The product of this gene belongs to the ficolin family of proteins. This family is characterized by the presence of a leader peptide, a short N-terminal segment, followed by a collagen-like region, and a C-terminal fibrinogen-like domain. This gene is predominantly expressed in the liver, and has been shown to have carbohydrate binding and opsonic activities. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.94).
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0113 (1717/152240) while in subpopulation AFR AF = 0.0367 (1523/41540). AF 95% confidence interval is 0.0351. There are 33 homozygotes in GnomAd4. There are 807 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 33 AR gene
