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 Benign. Variant got -9 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.63).
BP6
Variant 13-102618769-A-G is Benign according to our data. Variant chr13-102618769-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 544315.Status of the report is criteria_provided_single_submitter, 1 stars.
BP7
Synonymous conserved (PhyloP=-0.006 with no splicing effect.
BS1
Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.000046 (7/152248) while in subpopulation AMR AF= 0.000131 (2/15290). AF 95% confidence interval is 0.0000226. There are 0 homozygotes in gnomad4. There are 4 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
