Genes affected
F7 (HGNC:3544): (coagulation factor VII) This gene encodes coagulation factor VII which is a vitamin K-dependent factor essential for hemostasis. This factor circulates in the blood in a zymogen form, and is converted to an active form by either factor IXa, factor Xa, factor XIIa, or thrombin by minor proteolysis. Upon activation of the factor VII, a heavy chain containing a catalytic domain and a light chain containing 2 EGF-like domains are generated, and two chains are held together by a disulfide bond. In the presence of factor III and calcium ions, the activated factor then further activates the coagulation cascade by converting factor IX to factor IXa and/or factor X to factor Xa. Defects in this gene can cause coagulopathy. Alternative splicing results in multiple transcript variants encoding different isoforms that may undergo similar proteolytic processing to generate mature polypeptides.

Factor VII deficiency Pathogenic:1

Baylor Genetics
Significance:Likely pathogenic
Review Status:no assertion criteria provided
Collection Method:clinical testing

Our laboratory reported dual molecular diagnoses in F7 (NM_000131.4, c.1285G>A) and MECP2 (NM_004992.3, c.332G>A) in this individual with reported features of motor delay, intellectual disability, hypotonia, bilateral sensorineural hearing loss, skeletal abnormalities, hypertrichosis, and factor VII deficiency. The F7 variant has been previously found in patients with Factor VII deficiency (FA7D) [MIM:227500] (PMID 18976247), and is considered likely pathogenic. The patient's mother was similarly affected with factor VII deficiency and was homozygous for the variant. Heterozygotes are expected to be asymptomatic carriers. -

PreventionGenetics, part of Exact Sciences
Significance:Likely pathogenic
Review Status:no assertion criteria provided
Collection Method:clinical testing

The F7 c.1285G>A variant is predicted to result in the amino acid substitution p.Ala429Thr. This variant (aka p.Ala369Thr) has been reported in individuals with Factor VII deficiency (Herrmann et al 2009. PubMed ID: 18976247; Ravanbod et al. 2022. PubMed ID: 36760778; Pshenichnikova et al. 2023. PubMed ID: 37761907). A different missense substitution at this same codon (c.1286C>T, Ala429Val) has been reported in an individual with factor VII deficiency (Tang et al. 2022. PubMed ID: 35349734) suggesting that substitution of amino acid residue Ala429 is not tolerated. This variant is reported in 0.041% of alleles in individuals of Latino descent in gnomAD. This variant is interpreted as likely pathogenic. -
