Genes affected

TAB2 (HGNC:17075): (TGF-beta activated kinase 1 (MAP3K7) binding protein 2) The protein encoded by this gene is an activator of MAP3K7/TAK1, which is required for for the IL-1 induced activation of nuclear factor kappaB and MAPK8/JNK. This protein forms a kinase complex with TRAF6, MAP3K7 and TAB1, and it thus serves as an adaptor that links MAP3K7 and TRAF6. This protein, along with TAB1 and MAP3K7, also participates in the signal transduction induced by TNFSF11/RANKl through the activation of the receptor activator of NF-kappaB (TNFRSF11A/RANK), which may regulate the development and function of osteoclasts. Studies of the related mouse protein indicate that it functions to protect against liver damage caused by chemical stressors. Mutations in this gene cause congenital heart defects, multiple types, 2 (CHTD2). Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2014]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -6 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), TAB2. . Gene score misZ 1.613 (greater than the threshold 3.09). Trascript score misZ 3.2149 (greater than threshold 3.09). GenCC has associacion of gene with congenital heart defects, multiple types, 2, polyvalvular heart disease syndrome, chromosome 6q24-q25 deletion syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.17448473).

BS1

Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.000028 (41/1461774) while in subpopulation NFE AF= 0.0000369 (41/1111956). AF 95% confidence interval is 0.0000274. There are 0 homozygotes in gnomad4_exome. There are 20 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAdExome4 at 41 AD gene.
