  • Title: Identification of an Arg35X mutation in the PDCD10 gene in a patient with cerebral and multiple spinal cavernous malformations.

    Journal: J Neurol Sci; 2008 Apr 15; 267(1-2):177-81. PubMed ID: 18035376.
    Abstract:
    Although cerebral cavernous malformations (CCMs) are not uncommon, the concurrent finding of cavernous malformations (CMs) both in the brain and spinal cord is quite rare. Furthermore, multiple spinal cord CMs are extremely rare with only a few cases being reported thus far. Recently, we encountered a 33-year-old Korean male with both CCM and multiple spinal intramedullary CMs. The patient complained of seizure and right chest paresthesia. The lesions were located throughout the neuraxis including the cerebral hemisphere, brain stem, and cervical and thoracic spinal cords. Molecular analysis of the KRIT1 (CCM1), CCM2, and PDCD10 (CCM3) genes identified a heterozygous nonsense mutation (c.103C>T; Arg35X) in the PDCD10 gene, which was reported previously in a CCM family. The patient denied a family history, however, his daughter had an identical mutation, but was asymptomatic. Three months later, after identifying the mutation in the father and the daughter, the daughter presented with seizure. To the best of our knowledge, this is the first report of an association between a mutation in the PDCD10 gene and spinal CMs.
