KRT16 and psoriasis: So, in order to predict the mutation in two stages of psoriasis, we have taken the K14, K10, K16, and K17 coding sequences of healthy population available in NCBI database with accession numbers NM_000526.4 (K14), NM_000421.3 (K10), NM_005557.3 (K16), and NM_000422.2 (K17), which were further aligned respectively with the Sanger sequences of K14, K10, K16, and K17 obtained in our patients by using BioEdit software (Additional file 1: Figs. S1 and S2).
