Genes affected

NEO1 (HGNC:7754): (neogenin 1) This gene encodes a cell surface protein that is a member of the immunoglobulin superfamily. The encoded protein consists of four N-terminal immunoglobulin-like domains, six fibronectin type III domains, a transmembrane domain and a C-terminal internal domain that shares homology with the tumor suppressor candidate gene DCC. This protein may be involved in cell growth and differentiation and in cell-cell adhesion. Defects in this gene are associated with cell proliferation in certain cancers. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Feb 2010]

The c.1180A>G (p.N394D) alteration is located in exon 7 (coding exon 7) of the NEO1 gene. This alteration results from a A to G substitution at nucleotide position 1180, causing the asparagine (N) at amino acid position 394 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
