Variant summary

Our verdict is Benign. The variant received -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBS1BS2

The NM_012293.3(PXDN):c.3593G>A(p.Arg1198Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0024 in 1,611,760 control chromosomes in the GnomAD database, including 82 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1198W) has been classified as Uncertain significance.

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]

Variant 2-1648187-C-T is Benign according to our data. Variant chr2-1648187-C-T is described in CliVar as Benign. Clinvar id is 471915.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr2-1648187-C-T is described in CliVar as Benign. Clinvar id is 471915.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr2-1648187-C-T is described in CliVar as Benign. Clinvar id is 471915.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 = 0.0124 (1891/152236) while in subpopulation AFR AF = 0.043 (1786/41538). AF 95% confidence interval is 0.0413. There are 39 homozygotes in GnomAd4. There are 886 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 39 AR gene
