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 GeneticsOct 12, 2021The c.122C>G (p.A41G) alteration is located in exon 3 (coding exon 2) of the XPOT gene. This alteration results from a C to G substitution at nucleotide position 122, causing the alanine (A) at amino acid position 41 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
