Genes affected

IPO11 (HGNC:20628): (importin 11) Importins, including IPO11, are a members of the karyopherin/importin-beta family of transport receptors (see KPNB1; 602738) that mediate nucleocytoplasmic transport of protein and RNA cargoes (Plafker and Macara, 2000 [PubMed 11032817]).[supplied by OMIM, Sep 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.269C>T (p.T90I) alteration is located in exon 3 (coding exon 3) of the IPO11 gene. This alteration results from a C to T substitution at nucleotide position 269, causing the threonine (T) at amino acid position 90 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
