Genes affected

MIEN1 (HGNC:28230): (migration and invasion enhancer 1) Involved in negative regulation of apoptotic process; positive regulation of cell migration; and positive regulation of filopodium assembly. Located in several cellular components, including centriolar satellite; cytosol; and nucleoplasm. Is intrinsic component of the cytoplasmic side of the plasma membrane.

MIEN1 links:

ERBB2 (HGNC:3430): (erb-b2 receptor tyrosine kinase 2) This gene encodes a member of the epidermal growth factor (EGF) receptor family of receptor tyrosine kinases. This protein has no ligand binding domain of its own and therefore cannot bind growth factors. However, it does bind tightly to other ligand-bound EGF receptor family members to form a heterodimer, stabilizing ligand binding and enhancing kinase-mediated activation of downstream signalling pathways, such as those involving mitogen-activated protein kinase and phosphatidylinositol-3 kinase. Allelic variations at amino acid positions 654 and 655 of isoform a (positions 624 and 625 of isoform b) have been reported, with the most common allele, Ile654/Ile655, shown here. Amplification and/or overexpression of this gene has been reported in numerous cancers, including breast and ovarian tumors. Alternative splicing results in several additional transcript variants, some encoding different isoforms and others that have not been fully characterized. [provided by RefSeq, Jul 2008]

The c.26C>T (p.S9F) alteration is located in exon 1 (coding exon 1) of the MIEN1 gene. This alteration results from a C to T substitution at nucleotide position 26, causing the serine (S) at amino acid position 9 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
