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: Benign. The variant received -13 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.0129981935).
BP6
Variant 17-58278036-G-A is Benign according to our data. Variant chr17-58278036-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 3630.
BS1
Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.0146 (21327/1461264) while in subpopulation NFE AF = 0.0165 (18356/1111998). AF 95% confidence interval is 0.0163. There are 222 homozygotes in GnomAdExome4. There are 10245 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 31 AR gene
