Genes affected

TFG (HGNC:11758): (trafficking from ER to golgi regulator) There are several documented fusion oncoproteins encoded partially by this gene. This gene also participates in several oncogenic rearrangements resulting in anaplastic lymphoma and mixoid chondrosarcoma, and may play a role in the NF-kappaB pathway. Multiple transcript variants have been found for this gene. [provided by RefSeq, Sep 2010]

ACMG classification

Verdict is Benign. Variant got -19 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.42).
• BP6: Variant 3-100736589-T-G is Benign according to our data. Variant chr3-100736589-T-G is described in ClinVar as [Likely_benign]. Clinvar id is 466410.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr3-100736589-T-G is described in Lovd as [Likely_benign].
• BP7: Synonymous conserved (PhyloP=1.57 with no splicing effect.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00404 (615/152248) while in subpopulation NFE AF= 0.00716 (487/68022). AF 95% confidence interval is 0.00663. There are 2 homozygotes in gnomad4. There are 253 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 2 AR gene

Ambry Genetics

Jul 11, 2019

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
