Genes affected

XPO7 (HGNC:14108): (exportin 7) The transport of protein and large RNAs through the nuclear pore complexes (NPC) is an energy-dependent and regulated process. The import of proteins with a nuclear localization signal (NLS) is accomplished by recognition of one or more clusters of basic amino acids by the importin-alpha/beta complex; see MIM 600685 and MIM 602738. The small GTPase RAN (MIM 601179) plays a key role in NLS-dependent protein import. RAN-binding protein-16 is a member of the importin-beta superfamily of nuclear transport receptors.[supplied by OMIM, Jul 2002]

Ambry Genetics

Feb 28, 2024

The c.398C>T (p.A133V) alteration is located in exon 4 (coding exon 4) of the XPO7 gene. This alteration results from a C to T substitution at nucleotide position 398, causing the alanine (A) at amino acid position 133 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
