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.1427G>A (p.S476N) alteration is located in exon 13 (coding exon 12) of the XPOT gene. This alteration results from a G to A substitution at nucleotide position 1427, causing the serine (S) at amino acid position 476 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
