Keratosis follicularis spinulosa decalvans (also known as "Siemens-1 syndrome") is a rare X-linked disorder described by Siemens in 1926, a disease that begins in infancy with keratosis pilaris localized on the face, then evolves to more diffuse involvement.[1]:580,762[2]:649,714[3]

An association with SAT1 has been suggested.[4]
