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 Benign. Variant got -12 ACMG points.

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=0.057059377).
BP6
Variant 7-128957286-G-A is Benign according to our data. Variant chr7-128957286-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 282446.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Benign=2, Uncertain_significance=1}.
BS1
Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.000657 (100/152316) while in subpopulation AMR AF= 0.0032 (49/15296). AF 95% confidence interval is 0.00249. There are 0 homozygotes in gnomad4. There are 63 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High AC in GnomAd4 at 100 AD gene.
