Genes affected

PADI6 (HGNC:20449): (peptidyl arginine deiminase 6) 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. This protein may play a role in cytoskeletal reorganization in the egg and in early embryo development. [provided by RefSeq, Sep 2012]

ACMG classification

Verdict is Benign. Variant got -7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.006461054).
• BP6: Variant 1-17373225-G-A is Benign according to our data. Variant chr1-17373225-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 1176184.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1}.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.000972 (148/152330) while in subpopulation NFE AF= 0.00179 (122/68032). AF 95% confidence interval is 0.00153. There are 0 homozygotes in gnomad4. There are 66 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
