Moriyama 2015. WES identified a novel non-sense ETV6 variant (p.Arg359X) with a high penetrance in an index family with 3 members of ALL (mother and 2 daughter, at the ages of 9, 3, and 2). 1 daughter with the same (11 yro then) did not have leukemia at the time when this manuscript was written, suggesting possible incomplete penetrance. Subsequent targeted sequencing of ETV6 in 4405 childhood ALL cases identified 31 exonic variants (four non-sense, 21 missense, one splice site, and five frameshift variants) that were potentially related to ALL risk in 35 cases (1%).

Rampersaud 2019. WGS identified a germline 75-bp deletion, removing ETV6 exon 7 splice acceptor, resulting in exon skipping and protein truncation, in 4 of 7 affected individuals from a kindred presenting with pre–B-cell ALL, diffuse large B-cell lymphoma (DLBCL), thrombocytopenia, and aplastic anemia.

Topka 2015. Sanger sequencing ETV6 p. N385fs (c.1153-5_1153_1delAACAG) was identified in 2 affected members from a kindred characterized by thrombocytopenia, ALL and secondary myelodysplasia/acute myeloid leukemia. FUNCTIONAL study showed leukemic cells from the proband in the second kindred showed deletion of wild type ETV6 with retention of the ETV6 p. N385fs. Enforced expression of the ETV6 mutants revealed normal transcript and protein levels, but impaired nuclear localization. Accordingly, these mutants exhibited significantly reduced ability to regulate the transcription of ETV6 target genes.

Melazzini 2016. ETV6 gene was analyzed using Sanger and whole exome sequencing in the 130 families with inherited thrombocytopenia of unknown origin. identified 5 ETV6 variants in 20 patients with ETV6-related thrombocytopenia from 7 pedigrees. One family (3 affected members) has a fs variant (c.1153-1_1165del/p.N385Vfs*7) which resulting in skipping of e7 and truncation of the ETS domain.

Noetzli 2015. WES identified a splicing variant (c.1252A>G) in ETV6 segregating in 2 affected members from a family with thrombocytopenia and elevated MCV. This variant leads to skipping of exon 7 and a subsequent p.Asn385Valfs*7, affecting the putative DNA binding domain.

Guidugli 2017. NGS MDS/AL predisposition gene panel analysis in 197 patients identified a novel c.614del /p.Leu205Argfs4 in ETV6 gene in a patient with MDS/acute leukemia
HI Evidence Comments:
Haploinsufficiency of this ETV6 cause autosomal dominant ETV6 thrombocytopenia and predisposition to leukemia. Three more nonsense variants were reported by PMID: 32935436 and PMID: 31704777.
