Genes affected

IGSF8 (HGNC:17813): (immunoglobulin superfamily member 8) This gene encodes a member the EWI subfamily of the immunoglobulin protein superfamily. Members of this family contain a single transmembrane domain, an EWI (Glu-Trp-Ile)-motif and a variable number of immunoglobulin domains. This protein interacts with the tetraspanins CD81 and CD9 and may regulate their role in certain cellular functions including cell migration and viral infection. The encoded protein may also function as a tumor suppressor by inhibiting the proliferation of certain cancers. Alternate splicing results in multiple transcript variants that encode the same protein. [provided by RefSeq, Sep 2011]

The c.1444G>A (p.E482K) alteration is located in exon 5 (coding exon 5) of the IGSF8 gene. This alteration results from a G to A substitution at nucleotide position 1444, causing the glutamic acid (E) at amino acid position 482 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
