Cerebral cavernous malformations (CCMs) are clusters of abnormal blood vessels in the brain and spine. CCMs can bleed and cause strokes, seizures, and headaches. In the Hispanic population of the southwest, CCMs are often caused by an inherited gene mutation (alteration), termed the common Hispanic mutation (CCM1-CHM). There is a wide range of disease severity even among family members with this disease, though the natural history has not been clearly described for this particular population.

This study will examine factors that influence disease severity through the collection of blood samples, detailed medical histories, physical and neurological exam, and magnetic resonance imaging (MRI) of the brain. The specific goals of this study are to:

  1. establish a registry/database of familial CCM cases with detailed clinical data,
  2. perform genetic testing on participant blood samples to identify other genes that may influence the development and hemorrhage of CCM lesions, and
  3. determine lesion growth during the study.

Primary Outcome Measures:
  • Lesion number [ Time Frame: Baseline ] [ Designated as safety issue: No ]
    The number of lesions (or cavernous angiomas) located in the brain will be counted by a neuroradiologist.

Secondary Outcome Measures:
  • Change in lesion number [ Time Frame: Baseline, Follow up MRI ] [ Designated as safety issue: No ]
    The number of lesions (or cavernous angiomas) counted on the baseline MRI will be compared to the number of lesions observed in the follow up study MRI. This will only be performed for the first 100 participants in the study.

  • Neurological status [ Time Frame: Baseline ] [ Designated as safety issue: No ]
    The neurological status of participants will be evaluated by a neurologist.

Biospecimen Retention:   Samples With DNA
We collect and store saliva as well as whole blood for DNA and RNA extraction.

Estimated Enrollment: 500
Study Start Date: April 2010
Estimated Study Completion Date: June 2014
Estimated Primary Completion Date: June 2014 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
CCM1-CHM Participants
All individuals in the study have CCM1-CHM and will participate in the natural history data collection.
Other: Natural history data collection
Collection of detailed medical history, brain MRI, and neurological and physical examination.


Ages Eligible for Study:   6 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
The study population includes individuals who carry the cerebral cavernous malformation-common Hispanic mutation (CCM1-CHM). We are enrolling individuals who are symptomatic as well as those individuals with no symptoms. Although this disease is common in New Mexico, we are interested in enrolling individuals worldwide if they have CCM1-CHM.

Inclusion Criteria:

  • Diagnosis of cerebral cavernous malformations-common Hispanic mutation.

Exclusion Criteria:

  • Incarceration
  • Unable to pass MRI safety screening (pregnant females, claustrophobic, or those with certain metallic items implanted in their bodies)
  • Individuals who are unable to tolerate MRI without sedation, which refers mailed to children < 6 years old.
