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 GeneticsFeb 14, 2023The c.2537A>G (p.K846R) alteration is located in exon 17 (coding exon 17) of the XPO4 gene. This alteration results from a A to G substitution at nucleotide position 2537, causing the lysine (K) at amino acid position 846 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
