Genes affected
PXDN (HGNC:14966): (peroxidasin) This gene encodes a heme-containing peroxidase that is secreted into the extracellular matrix. It is involved in extracellular matrix formation, and may function in the physiological and pathological fibrogenic response in fibrotic kidney. Mutations in this gene cause corneal opacification and other ocular anomalies, and also microphthalmia and anterior segment dysgenesis. [provided by RefSeq, Aug 2014]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -20 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.87).
BP6
Variant 2-1634339-G-A is Benign according to our data. Variant chr2-1634339-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 1216923.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00974 (1484/152354) while in subpopulation AFR AF= 0.0344 (1429/41592). AF 95% confidence interval is 0.0329. There are 22 homozygotes in gnomad4. There are 688 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 22 AR gene
