Hereditary hemochromatosis (HHC), a disorder of iron overload, presents with clinical phenotypic heterogeneity. Complications can be mitigated with early intervention. The association between HHC and alopecia areata (AA) is unknown. We report 4 patients with HHC concurrent with AA. In 2 patients, the HHC diagnosis was revealed from the results of laboratory iron studies as part of an alopecia consultation workup. Alopecia areata may be a rare early cutaneous manifestation of HHC in individuals with a predisposition for autoimmunity; however, the genetic relationship between the 2 disorders is currently unknown. Patients at high risk for HHC such as those with a family history and/or those who fit the demographic profile may benefit from laboratory iron screening if they present to the clinic with AA.

Background: Alopecia areata (AA) is a common non-scarring hair loss disorder associated with autoimmune conditions. However, the pathobiology of AA is not well understood, and there is no targeted therapy available for AA. METHODS: In this study, differential gene expression analysis, immune status assessment, weighted correlation network analysis (WGCNA), and functional enrichment analysis were performed to identify shared genes associated with both immunological response and AA.

We previously demonstrated that C-X-C Motif Chemokine Ligand 12 (CXCL12) is primarily secreted by dermal fibroblasts in response to androgens and induces hair miniaturization in the mouse androgenic alopecia (AGA) model. However, the direct effects of androgen-induced CXCL12 on dermal papilla cells (DPCs) and dermal sheath cup cells (DSCs) have not been demonstrated. First, we compared single-cell RNA sequencing data between mouse and human skin, and the results show that CXCL12 is highly co-expressed with the androgen receptor (AR) in the DPCs and DSCs of only human hair.

Background: Alopecia areata (AA) is a chronic inflammatory disease that affects the hair follicles and sometimes the nails. It usually presents as a single or multiple patches of hair loss on the scalp, but any hair-bearing skin can be involved. AA treatment depends on the severity and extent of the disease.
