Genes affected

IPO13 (HGNC:16853): (importin 13) This gene encodes a member of the importin-beta family of nuclear transport proteins. The encoded protein mediates the import of specific cargo proteins from the cytoplasm to the nucleus and is dependent on the Ras-related nuclear protein-GTPase system. The encoded protein is also involved in nuclear export of the eukaryotic translation initiation factor 1A.[provided by RefSeq, Mar 2009]

Ambry Genetics

Nov 21, 2022

The c.2032G>T (p.V678L) alteration is located in exon 12 (coding exon 12) of the IPO13 gene. This alteration results from a G to T substitution at nucleotide position 2032, causing the valine (V) at amino acid position 678 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
