For example, Fang et al. [30] published in 2022 a study on 51 subjects coming from seven families with multiple endocrine neoplasia type 2 that was associated with lichen amyloidosis: females were more affected and the inter-scapular region was the most often described, while RET-C634 variant displayed the highest frequency, data that are consistent with our findings [30]. The gene discussed is RET; the disease is multiple endocrine neoplasia type 2.
