    ### Instruction:
    What are the genetic changes related to Naegeli-Franceschetti-Jadassohn syndrome/dermatopathia pigmentosa reticularis ?
    ### Response:
    NFJS/DPR results from mutations in the KRT14 gene. This gene provides instructions for making a protein called keratin 14. Keratins are tough, fibrous proteins that provide strength and resiliency to the outer layer of the skin (the epidermis). Researchers believe that keratin 14 may also play a role in the formation of sweat glands and the development of dermatoglyphs.
