Genes affected

PADI3 (HGNC:18337): (peptidyl arginine deiminase 3) This gene encodes a member of the peptidyl arginine deiminase family of enzymes, which catalyze the post-translational deimination of proteins by converting arginine residues into citrullines in the presence of calcium ions. The family members have distinct substrate specificities and tissue-specific expression patterns. The type III enzyme modulates hair structural proteins, such as filaggrin in the hair follicle and trichohyalin in the inner root sheath, during hair follicle formation. Together with the type I enzyme, this enzyme may also play a role in terminal differentiation of the epidermis. This gene exists in a cluster with four other paralogous genes.

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

PP5

Variant 1-17270928-C-T is Pathogenic according to our data. Variant chr1-17270928-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 374867.

BP4

Computational evidence support a benign effect (MetaRNN=0.02340281). . Strength limited to SUPPORTING due to the PP5.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00623 (948/152268) while in subpopulation NFE AF = 0.00932 (634/68008). AF 95% confidence interval is 0.00872. There are 7 homozygotes in GnomAd4. There are 463 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High Homozygotes in GnomAd4 at 7 AR,Unknown gene
