Genes affected

TPP2 (HGNC:12016): (tripeptidyl peptidase 2) This gene encodes a mammalian peptidase that, at neutral pH, removes tripeptides from the N terminus of longer peptides. The protein has a specialized function that is essential for some MHC class I antigen presentation. The protein is a high molecular mass serine exopeptidase; the amino acid sequence surrounding the serine residue at the active site is similar to the peptidases of the subtilisin class rather than the trypsin class.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), TPP2. . Gene score misZ 3.8614 (greater than the threshold 3.09). Trascript score misZ 4.5709 (greater than threshold 3.09). GenCC has associacion of gene with autoimmune hemolytic anemia-autoimmune thrombocytopenia-primary immunodeficiency syndrome, immunodeficiency 78 with autoimmunity and developmental delay.

BP4

Computational evidence support a benign effect (MetaRNN=0.142679).
