Genes affected

XPO4 (HGNC:17796): (exportin 4) XPO4 belongs to a large family of karyopherins (see MIM 602738) that mediate the transport of proteins and other cargo between the nuclear and cytoplasmic compartments (Lipowsky et al., 2000 [PubMed 10944119]).[supplied by OMIM, Mar 2009]

The c.2167T>A (p.C723S) alteration is located in exon 16 (coding exon 16) of the XPO4 gene. This alteration results from a T to A substitution at nucleotide position 2167, causing the cysteine (C) at amino acid position 723 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
