Genes affected

XPO6 (HGNC:19733): (exportin 6) The protein encoded by this gene is a member of the importin-beta family. Members of this family are regulated by the GTPase Ran to mediate transport of cargo across the nuclear envelope. This protein has been shown to mediate nuclear export of profilin-actin complexes. A pseudogene of this gene is located on the long arm of chromosome 14. Alternative splicing results in multiple transcript variants that encode different protein isoforms.

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, XPO6
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.884

The c.1409T>G (p.L470R) alteration is located in exon 10 (coding exon 10) of the XPO6 gene. This alteration results from a T to G substitution at nucleotide position 1409, causing the leucine (L) at amino acid position 470 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
