Variant summary

Our verdict is Likely benign. Variant got -5 ACMG points: 1P and 6B. PP2BP4_ModerateBS2

The NM_001081550.2(THOC2):​c.4766C>T​(p.Ser1589Leu) variant causes a missense change. The variant allele was found at a frequency of 0.0000073 in 1,095,209 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 3 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. S1589S) has been classified as Benign.

Genes affected
THOC2 (HGNC:19073): (THO complex subunit 2) The TREX multiprotein complex binds specifically to spliced mRNAs to facilitate mRNA export. The protein encoded by this gene is a member of the THO complex, a subset of the TREX complex. The encoded protein interacts with the THOC1 protein.[provided by RefSeq, Jun 2010]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), THOC2. . Gene score misZ 5.5258 (greater than the threshold 3.09). GenCC has associacion of gene with X-linked intellectual disability-short stature-overweight syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.25140375).
BS2
High Hemizygotes in GnomAdExome4 at 3 XL gene

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingGeneDxApr 09, 2019Has not been previously published as pathogenic or benign to our knowledge; In-silico analysis, which includes splice predictors and evolutionary conservation, is inconclusive as to whether the variant alters gene splicing. In the absence of RNA/functional studies, the actual effect of this sequence change is unknown. -
