Pathogenic variations in the NTRK1 can cause congenital insensitivity to pain with anhidrosis (CIPA), a rare autosomal recessive inherited neuropathy. The precise diagnosis of CIPA relies on the identification of pathogenic genotypes. Therefore, it is essential to expand the NTRK1 variation spectrum and improve molecular diagnosis methods. ⋯ When combined with data from another 53 CIPA patients examined in our previous work, this study establishes the largest genotypic and phenotypic spectra of CIPA worldwide, including 127 CIPA families. Moreover, functional studies indicated that the pathogenicity of VUS mainly affected insufficient glycosylation in the extracellular domain and abnormal phosphorylation in the intracellular domain. This study not only provides important evidence for precise diagnosis of CIPA but also further enriches our understanding of the pathogenesis of this disease.

Research has consistently suggested that media consumption plays a vital role in children's socialization, including the socialization of painful experiences. Past research examining young children's popular media revealed worrisome trends in media depictions of pain; it consisted of narrow depictions of pain, gender stereotypes, and an overwhelming lack of empathy from observers, which could contribute to pain-related stigma. Research has not yet examined how pain is portrayed in adolescent media, despite adolescence being the developmental period when chronic pain often emerges. ⋯ Furthermore, regardless of observed gender or "race," observers displayed a lack of empathy for sufferers and rarely engaged in prosocial behaviors. Popular media may serve as an agent of socialization in adolescence; thus, pain depictions may be a powerful force in propagating pain-related stigma and inequities. An opportunity exists to harness popular media to adaptively and accurately portray pain to adolescents.
