SOX10

The SOX gene encodes for transcription factors that are involved in embryogenesis and cell differentiation. Specifically, SOX10 aids with neural crest shuttling and development. In diagnostic histopathology, Sox10 immunostain is a helpful ancillary test due to its high sensitivity for melanocytic and peripheral nerve sheath neoplasms, and its role in distinguishing triple-negative breast carcinomas from gynaecological carcinoma, cutaneous adnexal neoplasms and salivary glands neoplasms from histological mimics.
