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]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 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 domain Peptidase S1 (size 235) in uniprot entity FA11_HUMAN there are 33 pathogenic changes around while only 1 benign (97%) in NM_000128.4
• PM2: Very rare variant in population databases, with high coverage
