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

Dec 06, 2021

The c.3371C>T (p.T1124M) alteration is located in exon 23 (coding exon 23) of the XPO4 gene. This alteration results from a C to T substitution at nucleotide position 3371, causing the threonine (T) at amino acid position 1124 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
