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 5 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.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.901
