Genes affected

TDP2 (HGNC:17768): (tyrosyl-DNA phosphodiesterase 2) This gene encodes a member of a superfamily of divalent cation-dependent phosphodiesterases. The encoded protein associates with CD40, tumor necrosis factor (TNF) receptor-75 and TNF receptor associated factors (TRAFs), and inhibits nuclear factor-kappa-B activation. This protein has sequence and structural similarities with APE1 endonuclease, which is involved in both DNA repair and the activation of transcription factors. [provided by RefSeq, Jul 2008]

TDP2 Gene-Disease associations (from GenCC):

spinocerebellar ataxia, autosomal recessive 23

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

PP3

Splicing predictors support a deleterious effect. Scorers claiming Pathogenic: dbscSNV1_ADA, dbscSNV1_RF, max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.

BS1

Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.000011 (15/1367792) while in subpopulation AMR AF = 0.000313 (10/31980). AF 95% confidence interval is 0.000169. There are 0 homozygotes in GnomAdExome4. There are 8 alleles in the male GnomAdExome4 subpopulation. Median coverage is 20. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
