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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 22, 2023The c.1676C>T (p.P559L) alteration is located in exon 13 (coding exon 13) of the XPO4 gene. This alteration results from a C to T substitution at nucleotide position 1676, causing the proline (P) at amino acid position 559 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
