Genes affected
XPOT (HGNC:12826): (exportin for tRNA) This gene encodes a protein belonging to the RAN-GTPase exportin family that mediates export of tRNA from the nucleus to the cytoplasm. Translocation of tRNA to the cytoplasm occurs once exportin has bound both tRNA and GTP-bound RAN. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 26, 2022The c.1678A>T (p.N560Y) alteration is located in exon 16 (coding exon 15) of the XPOT gene. This alteration results from a A to T substitution at nucleotide position 1678, causing the asparagine (N) at amino acid position 560 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
