Genes affected
IPO13 (HGNC:16853): (importin 13) This gene encodes a member of the importin-beta family of nuclear transport proteins. The encoded protein mediates the import of specific cargo proteins from the cytoplasm to the nucleus and is dependent on the Ras-related nuclear protein-GTPase system. The encoded protein is also involved in nuclear export of the eukaryotic translation initiation factor 1A.[provided by RefSeq, Mar 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 21, 2024The c.848T>C (p.I283T) alteration is located in exon 3 (coding exon 3) of the IPO13 gene. This alteration results from a T to C substitution at nucleotide position 848, causing the isoleucine (I) at amino acid position 283 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
