Genes affected

FN1 (HGNC:3778): (fibronectin 1) This gene encodes fibronectin, a glycoprotein present in a soluble dimeric form in plasma, and in a dimeric or multimeric form at the cell surface and in extracellular matrix. The encoded preproprotein is proteolytically processed to generate the mature protein. Fibronectin is involved in cell adhesion and migration processes including embryogenesis, wound healing, blood coagulation, host defense, and metastasis. The gene has three regions subject to alternative splicing, with the potential to produce 20 different transcript variants, at least one of which encodes an isoform that undergoes proteolytic processing. The full-length nature of some variants has not been determined. [provided by RefSeq, Jan 2016]

FN1 links:

ATIC (HGNC:794): (5-aminoimidazole-4-carboxamide ribonucleotide formyltransferase/IMP cyclohydrolase) This gene encodes a bifunctional protein that catalyzes the last two steps of the de novo purine biosynthetic pathway. The N-terminal domain has phosphoribosylaminoimidazolecarboxamide formyltransferase activity, and the C-terminal domain has IMP cyclohydrolase activity. A mutation in this gene results in AICA-ribosiduria. [provided by RefSeq, Sep 2009]

This sequence change creates a premature translational stop signal (p.Arg2476*) in the FN1 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 2 amino acid(s) of the FN1 protein. This variant is present in population databases (rs146924311, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with FN1-related conditions. ClinVar contains an entry for this variant (Variation ID: 2076277). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
