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]

Ambry Genetics

Mar 07, 2023

The c.2036T>C (p.I679T) alteration is located in exon 15 (coding exon 15) of the XPO4 gene. This alteration results from a T to C substitution at nucleotide position 2036, causing the isoleucine (I) at amino acid position 679 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
