Home Search Sitemap Contact ... Back January 30, 2001 Mouse with Iron Disorder Offers Clues to Parkinson's, Similar Diseases Mice engineered to lack a gene involved in iron metabolism may provide important clues for deciphering the nature of a group of brain disorders-similar to Parkinson's Disease-affecting movement, according to a study by researchers at the National Institute of Child Health and Human Development (NICHD). The researchers reported in the February issue of Nature Genetics that mice lacking the gene for iron regulatory protein 2 (IRP2) develop iron deposits in key areas of the brain. The progressive deterioration of the mice's nervous system is like that seen in people with Parkinson's Disease and Multiple System Atrophy (also known as Parkinson's Plus). "Researchers have long debated whether the characteristic iron deposits of these diseases are the cause or the result of the disease process," said Duane Alexander, M.D., Director of the NICHD. "This is a strong clue that iron may play a causative role in Parkinson's and similar disorders." Diseases in which excess brain iron has been observed include Parkinson's Disease, Friedreich's Ataxia and Hallervorden-Spatz disease. However, the brain areas affected differ from those in the IRP 2 deficient mice, and it is unlikely that IRP 2 is involved in these human diseases, said the study's senior investigator, Tracey A. Rouault, M.D., of NICHD's Cell Biology and Metabolism Branch. Still, the NICHD finding suggests that other genes involved in iron metabolism may be good candidates for investigations into the causes of these disorders.

The Spinocerebeller Ataxias The spinocerebellar ataxias are a group of autosomal dominantly inherited ataxias with heterogeneous presentation. Characteristic CAG repeat expansions in the coding sequences at several loci have been detected for certain of these disorders. Hence, a direct DNA test can provide an unequivocal diagnostic result for what are often complex clinical presentations. The loci reponsible for this group of disorders continues to grow and are the subject of research strategies evaluating trinucleotide (especially CAG trinucleotide) repeat expansions. A recent comprehensive clinical and molecular genetic reference is provided by Koshy and Zoghbi (1997), Brain Pathology 7:927-942. Although this is a recent review, it is out of date as the locus for SCA7 has been recently described (David et al. (1997) Nature Genetics 17:65-70; Koob et al. (1998) Nature Genetics 18:72-75.) The Table below provides a cross-reference of SCA genetic loci and a variety of alternative clinical names.

NAF Pamphlet - Sporadic OPCA This response submitted by on 1/1/98. Email Address: What is Sporadic Olivopontocerebellar Atrophy? Olivopontocerebellar atrophy (OPCA) is almost certainly not a single disease, but a group of diseases. In this brochure, we discuss OPCA that has occurred "sporadically", which means that no one else in the family has ever had the same disorder. In the brochure "Hereditary Olivopontocerebellar Atrophy", we describe forms of ataxia that are known to run in families. Many people do not receive a diagnosis of OPCA until they have seen many different physicians. Physicians also use different terms when they diagnose OPCA. Here is a list of some of the terms, or diagnoses, that physicians may use: * olivopontocerebellar atrophy or degeneration * olivocerebellar atrophy or degeneration * multisystem atrophy * ataxia * Marie's ataxia * Holmes ataxia * Menzel's ataxia * ataxia with Parkinsonism, autonomic neuropathy, corticospinal features or dementia * spastic ataxia In addition many patients with sporadic OPCA may have been diagnosed as having Parkinson's disease, multiple sclerosis, or

National Ataxia Foundation (NAF) What is the National Ataxia Foundation? The National Ataxia Foundation is a nonprofit organization established in 1957 with the primary mission of encouraging and supporting research into Hereditary Ataxia, a group of neurological disorders which are chronic and progressive conditions affecting coordination. There are more than 45 affiliated chapters and support groups throughout the U.S. and Canada. Who is NAF for? An estimated 150,000 people in the United States are affected by the hereditary and sporadic ataxias. They strike without regard to age, gender, or race. NAF's members include: people with hereditary or sporadic ataxia, their families, physicians and other health professionals who treat people with ataxia, physicians and scientists involved in research into the causes of ataxia, others interested in the fight against ataxia or in disability issues. (For people who have ataxia as a symptom of other medical conditions such as head injury, stroke, MS, or alcoholism, we recommend that you contact the organization related to your specific condition for the most up-to-date information. We will be happy to provide you with appropriate addresses and telephone numbers if needed.) What does NAF do?

Striatonigral degeneration is practically indistinguishable from Parkinson’s; OPCA is characterized by progressive ataxia (an inability to coordinate voluntary muscular movements) of the gait and arms and dysarthria (difficulty in articulating words); and Shy-Drager syndrome is characterized by Parkinsonism plus a much more pronounced failure of the autonomic nervous system. Striatonigral Degeneration Striatonigral degeneration is similar to Parkinson’s except tremor is much less common, and cerebellar ataxia (failure of muscle coordination) often develops over time. Pathologically, striatonigral degeneration is defined by abnormalities in the putamen and substantia nigra that are more extensive and localized than what is typical of Parkinson’s disease. Other portions of the basal ganglia (the part of the brain that is responsible for organization of motor movement) are also involved. Striatonigral degeneration is often indistinguishable from Parkinson’s except for the fact that it does not respond to medications that are used to treat the latter. MRI brain images sometimes reveal the severe degeneration of the affected structures and may provide additional diagnostic information.
