Variant summary

Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PS1_Moderate PM1 PM2 PP3_Strong

The NM_000128.4(F11):​c.1541G>T​(p.Cys514Phe) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,674 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another nucleotide change resulting in same amino acid change has been previously reported as Likely pathogenicin UniProt.

Genes affected

F11 (HGNC:3529): (coagulation factor XI) This gene encodes coagulation factor XI of the blood coagulation cascade. This protein is present in plasma as a zymogen, which is a unique plasma coagulation enzyme because it exists as a homodimer consisting of two identical polypeptide chains linked by disulfide bonds. During activation of the plasma factor XI, an internal peptide bond is cleaved by factor XIIa (or XII) in each of the two chains, resulting in activated factor XIa, a serine protease composed of two heavy and two light chains held together by disulfide bonds. This activated plasma factor XI triggers the middle phase of the intrisic pathway of blood coagulation by activating factor IX. Defects in this factor lead to Rosenthal syndrome, a blood coagulation abnormality. [provided by RefSeq, Jul 2008]

F11-AS1 (HGNC:27725): (F11 antisense RNA 1)

ACMG classification

Verdict is Pathogenic. Variant got 10 ACMG points.

• PS1: Transcript NM_000128.4 (F11) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in UniProt
• PM1: In a disulfide_bond (size 67) in uniprot entity FA11_HUMAN there are 8 pathogenic changes around while only 0 benign (100%) in NM_000128.4
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.972

Variant summary: F11 c.1541G>T (p.Cys514Phe) results in a non-conservative amino acid change located in the Serine proteases, trypsin domain (IPR001254) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 251442 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.1541G>T has been reported in the literature in at-least one heterozygous individual affected with factor XI deficiency disease (example: Gueguen_2012). These data do not allow any conclusion about variant significance. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication has been ascertained in the context of this evaluation (PMID: 22159456). ClinVar contains an entry for this variant (Variation ID: 68183). Based on the evidence outlined above, the variant was classified as uncertain significance. -
