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.1066C>T (p.H356Y) alteration is located in exon 9 (coding exon 8) of the XPOT gene. This alteration results from a C to T substitution at nucleotide position 1066, causing the histidine (H) at amino acid position 356 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
