Genes affected
TNPO1 (HGNC:6401): (transportin 1) This gene encodes the beta subunit of the karyopherin receptor complex which interacts with nuclear localization signals to target nuclear proteins to the nucleus. The karyopherin receptor complex is a heterodimer of an alpha subunit which recognizes the nuclear localization signal and a beta subunit which docks the complex at nucleoporins. Alternate splicing of this gene results in several transcript variants encoding different proteins. [provided by RefSeq, Jun 2018]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), TNPO1. . Gene score misZ 4.3261 (greater than the threshold 3.09). Trascript score misZ 4.9328 (greater than threshold 3.09). GenCC has associacion of gene with Tourette syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.29481882).

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 15, 2023The c.1378G>T (p.A460S) alteration is located in exon 13 (coding exon 13) of the TNPO1 gene. This alteration results from a G to T substitution at nucleotide position 1378, causing the alanine (A) at amino acid position 460 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
