Genes affected

MPO (HGNC:7218): (myeloperoxidase) Myeloperoxidase (MPO) is a heme protein synthesized during myeloid differentiation that constitutes the major component of neutrophil azurophilic granules. Produced as a single chain precursor, myeloperoxidase is subsequently cleaved into a light and heavy chain. The mature myeloperoxidase is a tetramer composed of 2 light chains and 2 heavy chains. This enzyme produces hypohalous acids central to the microbicidal activity of neutrophils. [provided by RefSeq, Nov 2014]

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 7 ACMG points.

PP3

Multiple lines of computational evidence support a deleterious effect 8: AlphaMissense, BayesDel_noAF, Cadd, Dann, Eigen, PROVEAN, REVEL, REVEL [when BayesDel_addAF, max_spliceai, FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]

PP5

Variant 17-58272835-G-A is Pathogenic according to our data. Variant chr17-58272835-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 3626.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP4

Computational evidence support a benign effect (MetaRNN=0.112965494). . Strength limited to SUPPORTING due to the PP5.

BS2

High Homozygotes in GnomAdExome4 at 5 AR geneVariant has number of homozygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
