Kazmina (Kezminova, Distraction) dystrophy Di-stractional dys-tro-fi-I calyx-spongy desmia of the spine 9 letters. A.A. I.K. Kazmin Kazmina is a rare combined hereditary disease of the spine (dysplasia and degeneration), combined with a congenital bone defect of the lower jaw. The cause of the atypical distraction form is a cellular barrier defect in the area of clefting of the bottom of the sella turcica or cervical semiarch. There are foci of excitation of GABAergic neurons that activate the generation of an excitatory neurotransmitter, causing degeneration of the cervical intervertebral discs of the distal and middle segments of the spine in children. The spread of the disease is controlled by gender.
