Genes affected

TNPO3 (HGNC:17103): (transportin 3) The protein encoded by this gene is a nuclear import receptor for serine/arginine-rich (SR) proteins such as the splicing factors SFRS1 and SFRS2. The encoded protein has also been shown to be involved in HIV-1 infection, apparently through interaction with the HIV-1 capsid protein. Several protein-coding and non-coding transcript variants have been found for this gene. [provided by RefSeq, Apr 2020]

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), TNPO3. . Gene score misZ 3.442 (greater than the threshold 3.09). Trascript score misZ 3.4155 (greater than threshold 3.09). GenCC has associacion of gene with autosomal dominant limb-girdle muscular dystrophy type 1F.

BP4

Computational evidence support a benign effect (MetaRNN=0.29197335).

The c.2708C>G (p.T903S) alteration is located in exon 21 (coding exon 21) of the TNPO3 gene. This alteration results from a C to G substitution at nucleotide position 2708, causing the threonine (T) at amino acid position 903 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
