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]

The c.1283G>A (p.R428H) alteration is located in exon 12 (coding exon 11) of the XPOT gene. This alteration results from a G to A substitution at nucleotide position 1283, causing the arginine (R) at amino acid position 428 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
