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.

The c.508C>T (p.H170Y) alteration is located in exon 5 (coding exon 5) of the PADI3 gene. This alteration results from a C to T substitution at nucleotide position 508, causing the histidine (H) at amino acid position 170 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
