RT Journal Article SR Electronic T1 Neuronal ceroid lipofuscinosis and arthropathy: a family study. JF Journal of Medical Genetics JO J Med Genet FD BMJ Publishing Group Ltd SP 101 OP 104 DO 10.1136/jmg.18.2.101 VO 18 IS 2 A1 Proops, R A1 Green, S H YR 1981 UL http://jmg.bmj.com/content/18/2/101.abstract AB A family is described in which three children have neuronal ceroid lipofuscinosis and two of them also have an arthropathy. Clinically the children have the late infantile form but pathological evidence shows the recognised overlap with the juvenile form. A fourth child with joint involvement but with normal skin biopsies is described. It is suggested that this family have a specific form of neuronal ceroid lipofuscinosis with arthropathy and that accumulation of metabolites in this storage disease may be age dependent.
