Representative images of buccal mucosa smears from a control and 3 children with a clinical presentation of ACM. Patient 1 (DSP mut) shows depressed immunoreactive signal for Cx43 and DSP but control-like signal for PG and PKP1. Patient 2 (PKP2 mut) shows depressed immunoreactive signal for PG, Cx43 and DSP but not PKP1 compared to age-matched controls. Patient 3 (DSP mut) shows depressed signal for DSP but control-like signal for PG, Cx43 and PKP1. Protein localization was unaltered between serial swabs. Cell nuclei (blue) are stained with DAPI.
