Genes affected

IPO8 (HGNC:9853): (importin 8) The importin-alpha/beta complex and the GTPase Ran mediate nuclear import of proteins with a classical nuclear localization signal. The protein encoded by this gene is a member of a class of approximately 20 potential Ran targets that share a sequence motif related to the Ran-binding site of importin-beta. This protein binds to the nuclear pore complex and, along with RanGTP and RANBP1, inhibits the GAP stimulation of the Ran GTPase. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2010]

The c.3089T>A (p.F1030Y) alteration is located in exon 25 (coding exon 25) of the IPO8 gene. This alteration results from a T to A substitution at nucleotide position 3089, causing the phenylalanine (F) at amino acid position 1030 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
