Single-cell RNA sequencing (scRNA-seq) provides an opportunity to decipher potential cell-cell interactions and cell-type specific transcriptomic changes, amenable to therapeutic intervention, particularly in rare diseases with heterogenous clinical presentations and lacking experimental animal models, such as SCADR. We performed scRNA-seq on the skin of four patients diagnosed with SCADR syndromes including one toxic epidermal necrolysis (TEN), one Stevens-Johnson syndrome (SJS), one acute generalized exanthematous pustulosis (AGEP), and one extensive drug-related maculopapular rash (MPR), and three healthy controls.2026/06/01GSE235512GSM7504440GSM7504450GSM7504442GSM7504441GSM7504448GSM7504437GSM7504447GSM7504439GSM7504449GSM7504438GSM7504444GSM7504443GSM7504446GSM750444520301235512Homo sapiens
