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]

PADI6-related disorder Pathogenic:1
Likely pathogenic, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesJun 06, 2023The PADI6 c.441dupA variant is predicted to result in a frameshift and premature protein termination (p.Trp148Metfs*20). To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0032% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/1-17707541-G-GA). Frameshift variants in PADI6 are expected to be pathogenic. This variant is interpreted as likely pathogenic. -
