YTHDC1 and epidermolysis bullosa simplex: In this pilot study, we investigated the gene expression of key regulators of m6A, such as writers Methyltransferase-like 3 and 4 (METTL3 and METTL14), readers YTH domain-containing proteins (YTHDC1, YTHDC2, YTHDC3) and YTH domain-containing family proteins ( YTHDF1 and YTHDF2) and erasers fat mass and obesity-associated (FTO) and alkB homolog 5 (ALKBH5), as well as total RNA m6A levels in the EB keratinocites cell line (KEB-7) derived from a patient with severe EBS, carrying the KRT14 R125P mutation.
