Genes affected
XPO1 (HGNC:12825): (exportin 1) This cell-cycle-regulated gene encodes a protein that mediates leucine-rich nuclear export signal (NES)-dependent protein transport. The protein specifically inhibits the nuclear export of Rev and U snRNAs. It is involved in the control of several cellular processes by controlling the localization of cyclin B, MPAK, and MAPKAP kinase 2. This protein also regulates NFAT and AP-1.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2024The c.2235T>G (p.I745M) alteration is located in exon 19 (coding exon 18) of the XPO1 gene. This alteration results from a T to G substitution at nucleotide position 2235, causing the isoleucine (I) at amino acid position 745 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
