Patients of any age with NPC may be eligible for this study. Participants undergo the following procedures every 6 months during 4- to 5-day admissions at the NIH Clinical Center.
-Medical evaluation, including medical history, physical exam, neurological exam, neuropsychometric evaluation, and blood and urine tests.
-Lumbar puncture (spinal tap): A sample of cerebrospinal fluid (CSF), the fluid that bathes the brain and spinal cord, is obtained for study. After administration of a local anesthetic, a small needle is inserted in the space between the bones in the lower back where the CSF circulates below the spinal cord. A small amount of fluid is collected through the needle.
-Eye exam and eye movement study: The pupils of the eye are dilated to examine the structures of the eyes. For the eye movement study a special contact lens is placed on the eye and the patient looks at a series of target light spots moving on a screen.
-Hearing tests.
-Electroretinography (in patients who can cooperate with the test) to measure the function of the retina. Before the test, the patient's pupils are dilated and an electrode (small silver disk) is taped to the forehead. The patient sits in a dark room for 30 minutes and then a special contact lens is placed on one eye after it has been numbed with drops. The contact lens senses small electrical signals generated by the retina when lights flash. During the ERG recording, the eye is stimulated with flashes of light projected inside a hollow sphere. After the test, a full eye exam is done and photographs of the retina are taken.
-Magnetic resonance imaging (MRI): This test uses a magnetic field and radio waves to produce images of the brain and obtain information about brain chemicals. The patient lies on a table that can slide in and out of the scanner (a narrow cylinder), wearing earplugs to muffle loud knocking and thumping sounds that occur during the scanning process. Patients who cannot remain still in the scanner may be sedated for the test.
-Psychometric testing: Patients complete questionnaires.
-Photographs of the patient may be taken for use in teaching sessions or scientific presentations or publications, with the patient's consent. Patients may be recognizable, but are not identified by name.
-Pregnancy test in all female patients over 10 years of age at the beginning of each admission to the Clinical Center.

INCLUSION CRITERIA: Affected Subjects The following individuals may be enrolled as in this study: - All patients with an established diagnosis of NPC (biochemical or molecular). - Both NPC1 and NPC2 patients. - Patients of any age - Males or females - Any ethnic background EXCLUSION CRITERIA: Individuals will not be enrolled in this study if: - they cannot travel to the NIH because of their medical condition or are too ill to be cared for at home. - they have rapidly progressive neonatal cholestasis. - they are pregnant (a negative urine pregnancy test will be required for any menstruating female before participation in this study and at each NIH Clinical Center admission). Unaffected Subjects Individuals may be enrolled for data and biospecimen collection if: - They are a known NPC1 or NPC2 heterozygote and consent to specimen collection (as specified in the protocol) from the carrier population. - There is no diagnosis or suspicion of NPC disease and consent is provided to be included in control or caregiver population. Individuals will not be enrolled for biospecimen collection if: - Consent is not provided - They have a contraindication to the method of specimen collection **Patients will be excluded from the MRI section of the study if they have a contraindication to MRI or if they do not meet the safety criteria established by the NIH Clinical Center radiology department for MRI scanning.
