Abstract
Huntington's disease (HD) is a neurodegenerative disorder with a midlife onset. The disease is caused by expansion of a CAG (glutamine) repeat within the coding region of the HD gene. The molecular mechanism by which the mutated protein causes this disease is still unclear. To study the protein we have generated a set of rabbit polyclonal antibodies raised against different segments of the N-terminal, central and C-terminal parts of the protein. The polyclonal antibodies were affinity purified and characterized in ELISA and Western blotting experiments. All antibodies can react with mouse and human proteins. The specificity of these antibodies is underscored by their recognition of huntingtin with different repeat sizes in extracts prepared from patient-derived lymphoblasts. The antibodies were used in immunofluorescence experiments to study the subcellular localization of huntingtin in mouse neuroblastoma NIE-115 cells. The results indicate that most huntingtin is present in the cytoplasm, whereas a minor fraction is present in the nucleus. On differentiation of the NIE-115 cells in vitro, the subcellular distribution of huntingtin does not change significantly. These results suggest that full-length huntingtin with a normal repeat length can be detected in the nucleus of cycling and non-cycling cultured mammalian cells of neuronal origin. However, in HD autopsy brain the huntingtin-containing neuronal intranuclear inclusions can be detected only with antibodies raised against the N-terminus of huntingtin. Thus several forms of huntingtin display the propensity for nuclear localization, possibly with different functional consequences.

Abstract
To determine the presence and distribution of cerebrovascular Abeta production we investigated amyloid beta precursor protein (AbetaPP)-mRNA expression by RNA in situ hybridization in patients with hereditary cerebral hemorrhage with amyloidosis, Dutch type, Alzheimer disease and controls. In all subjects, AbetaPP-mRNA was expressed in endothelial cells, smooth muscle cells, adventitial cells and brain pericytes and/or perivascular cells. Meningeal cells also expressed AbetaPP-mRNA. AbetaPP was detected in endothelial cells, smooth muscle cells and adventitial cells. The demonstration of AbetaPP-mRNA at all vascular sites where amyloid formation can occur supports an important contribution of locally derived Abeta to cerebrovascular amyloidosis.

Abstract
Lewy bodies (LB) and pale bodies (PB), their putative precursors, can be found in a spectrum of diseases characterized by parkinsonism and/or dementia. Furthermore, LB are occasionally observed in some other neurodegenerative diseases and in normal aging. Classical LB are typically found in the brain stem, especially in the substantia nigra, where these inclusions are associated with neuronal loss and clinical signs of idiopathic Parkinson's disease (PD). The so-called cortical LB occur in the cerebral cortex, amygdala and claustrum with little or no neuronal loss and are clinically associated with dementia in dementia with LB (DLB). We describe a patient without apparent clinical signs of parkinsonism and/or dementia, whose brain contained numerous classical-like LB, pale inclusions with features of PB and transitions between these two. These inclusions had similar immunohistological (ubiquitin positive; neurofilament positive; tau negative) and ultrastructural features as the LB in PD and DLB except for the lack of immunoreactivity for alpha-synuclein. The pons and cerebral cortex showed the highest number of LB, up to 165/1.76 mm2. These numbers were contrasted by the lack of obvious neuronal loss or gliosis. The absence of alpha-synuclein reactivity in the LB in this symptomless patient corroborates the hypothesis that alpha-synuclein accumulation in LB is an important step in neurodegeneration in PD and DLB, but tones down the role of alpha-synuclein in LB formation in general. This patient seems to represent a new variant in the spectrum of diseases associated with LB.

Abstract
BACKGROUND AND PURPOSE Microvascular changes such as microaneurysms and fibrinoid necrosis have been found in the presence of cerebral amyloid angiopathy (CAA). These CAA-associated microvasculopathies (CAA-AM) may contribute to the development of CAA-associated hemorrhages and/or infarcts, hereafter referred to as "cerebrovascular lesions." Hereditary cerebral hemorrhage with amyloidosis, Dutch type (HCHWA-D) is an autosomal dominant form of CAA, in which the amyloid angiopathy is pathologically and biochemically similar to sporadic CAA associated with aging and Alzheimer disease. To determine the significance of CAA-AM for CAA-associated cerebrovascular complications, we investigated the association between CAA-AM and cerebrovascular lesions in HCHWA-D patients. METHODS In a previous autopsy study we semiquantitatively scored CAA-AM in 29 HCHWA-D patients. In the present study we reviewed clinical charts and autopsy protocols of these same patients. We investigated whether CAA-AM was associated with age at death, number of cerebrovascular lesions, duration of clinical illness, hypertension, and atherosclerosis. RESULTS An association was found between CAA-AM and the number of cerebrovascular lesions (P = 0.009). The presence of microaneurysmal degeneration was most strongly associated with the number of cerebrovascular lesions (P < 0.001). In addition, we found an association between atherosclerosis and the CAA-AM score (P = 0.047). Hypertension was not associated with CAA-AM. CONCLUSIONS Our findings support previous reports suggesting an important role of secondary microvascular degenerative changes in CAA-associated cerebrovascular lesions and suggest an aggravating effect of systemic atherosclerosis, but not hypertension, on the evolution of CAA-AM. These findings may be of relevance to understanding cerebrovascular complications of sporadic or Alzheimer disease-associated CAA.

Abstract
Very long chain acyl-coenzyme A (acyl-CoA) dehydrogenase (VLCAD) deficiency is a severe disorder of mitochondrial beta-oxidation in infants. We report adult onset of attacks of painful rhabdomyolysis. Gas chromatography identified strongly elevated levels of tetradecenoic acid, 14:1(n-9), tetradecadienoic acid, 14:2(n-6), and hexadecadienoic acid, 16:2(n-6). Palmitoyl-CoA and behenoyl-CoA dehydrogenase in fibroblasts were deficient. Muscle VLCAD activity was very low. DNA analysis revealed compound heterozygosity for two missense mutations in the VLCAD gene. The relatively mild clinical course may be due to residual enzyme activity as a consequence of the two missense mutations. Treatment with L-carnitine and medium chain triglycerides in the diet did not reduce the attacks of rhabdomyolysis.

Abstract
In 3 patients, a 72-year-old man, a 62-year-old man and a 73-year-old woman with weakness of respectively the quadriceps femoris, the finger flexors and the pharyngeal muscles, the diagnosis of 'inclusion body myositis' was made. This is a rare, slowly progressive skeletal muscle disorder which is more common in men and after the age of fifty. The activity of serum creatine kinase is often 2-5 times the highest normal value. The electromyogram pattern is myopathic, but can also display neuropathic changes (exclusively). Inclusion body myositis is often misdiagnosed, which can lead to an inappropriate treatment or approach. A frozen muscle biopsy is needed to make cryostat sections for demonstration of myositis with rimmed vacuoles.

Abstract
Various secondary microvascular degenerative and inflammatory alterations may complicate cerebral amyloid angiopathy (CAA) and contribute to the morbidity of CAA-associated stroke. We have investigated the severity of CAA-associated microangiopathy in a genetically determined Dutch form of CAA (HCHWA-D) that has major similarities to the type of CAA that more commonly occurs with aging or Alzheimer's disease (AD). The presence and extent of the following vascular abnormalities was assessed: (1) hyalinization/fibrosis, (2) microaneurysm formation, (3) chronic (especially lymphocytic) inflammation, (4) perivascular multinucleated giant cells/granulomatous angiitis, (5) macrophages/histiocytes within the vessel wall, (6) vessel wall calcification, (7) fibrinoid necrosis, and (8) mural or occlusive thrombi. (Of these, calcification of CAA-affected vessel walls has, to our knowledge, been described in only a single patient with CAA-associated cerebral hemorrhage.) Some of the changes, such as histiocytes in blood vessel walls and the relationship of vascular hyalinosis to amyloid beta/A4 protein deposition, were highlighted by immunohistochemistry. By assessing the numbers of sections in which the changes were present for each case, a 'score' reflective of CAA-associated angiopathy could be obtained. This 'score' was reproducible among several observers. We suggest that it might also be applicable to quantifying severe CAA and related microvascular degenerative changes in patients with AD. beta/A4 immunoreactivity was often sparse and adventitial (or almost absent) in severely hyalinized arterioles and microaneurysms. However, macrophages were prominent in the walls of such vessels and may play a role in the pathogenesis and progression of CAA-related microvasculopathy.

Abstract
OBJECTIVE To determine the diagnostic value of perivascular infiltrates (PVI) in randomly obtained muscle biopsy specimens for the assessment of rheumatoid vasculitis (RV). METHODS The number and size of PVIs, defined as the presence of mononuclear or polymorphonuclear cells around > or = 50% of the circumference of a vessel wall, as well as the presence of fibrinoid necrosis were determined in frozen sections of muscle samples of RV patients with histologically confirmed vasculitis in fixed muscle tissue (n = 12). The findings were compared with those observed in frozen sections of muscle biopsy specimens of rheumatoid arthritis (RA) patients not suspected of vasculitis (n = 14) and patients with osteoarthritis (OA) (n = 11). The presence of PVIs and of fibrinoid necrosis were sought in four frozen sections of the muscle biopsy specimen. RESULTS PVIs were observed in 75% of the RV patients, which was significantly (p < 0.05) higher than the frequency found in RA (14%) or OA (18%) patients. PVIs with > or = three cell layers were found in 67% of the RV patients and in none of the RA and OA patients (p < 0.05). Fibrinoid necrosis was found in least one of four frozen section in 33% of the RV patients. There was a good intra-observer and inter-observer concordance on the presence of fibrinoid necrosis and of PVIs with > or = three cell layers. CONCLUSIONS The assessment of PVIs with > or = three cell layers in a muscle biopsy specimen is a specific and reliable test in discriminating RV from RA without vasculitis. The demonstration in muscle of PVIs with > or = three cell layers is more sensitive than that of fibrinoid necrosis in the diagnosis of RV.

Abstract
Oligoastrocytomas form a poorly defined subgroup of glial tumors, and few clinical series have been reported. We performed a retrospective study to elucidate the histopathological features of these tumors and to relate the clinical signs and symptoms and proliferative potential to survival. Oligoastrocytomas were defined as glial tumors with at least 10% neoplastic astrocytes and 10% neoplastic oligodendrocytes; tumors were graded with the St. Anne-Mayo criteria for astrocytomas and oligodendrogliomas. Proliferative potential was estimated with antibodies against proliferating cell nuclear antigen (PCNA). Median survival of 52 patients (median age, 42 years) was 75 weeks (range 2-703 weeks). Actuarial 1-, 2-, 3-, and 5-year survival rates were 67%, 43%, 40%, and 29%, respectively. For 15 patients with grade 3 and 33 with grade 4 lesions (St. Anne-Mayo astrocytoma classification), median survival was 217 and 55 weeks, respectively. For 19 patients with grade 2 and 33 with grade 3 lesions (St. Anne-Mayo oligodendroglioma classification), median survival was 305 and 55 weeks, respectively. Interobserver agreement between three experienced neuropathologists on identification of astrocytes, oligodendrocytes, and unclassifiable cells was low, indicating considerable subjectivity in the histopathological diagnosis. Median PCNA labeling indices correlated with tumor grade, but individual values varied so widely within grades that they had no predictive value for survival. In a multivariate analysis, symptoms of increased intracranial pressure and microvascular proliferation were independently associated with poor prognosis. The biological behavior of subgroups appeared to be distinctly less aggressive than that of 'pure' astrocytomas of similar grade. Better histopathological definition of oligoastrocytomas and improved assessment of percentages of constituent cell types may allow more accurate prognosis.

Abstract
Arterial and arteriolar amyloid-beta (A beta) deposition in hereditary cerebral hemorrhage with amyloidosis (Dutch) (HCHWA-D) and Alzheimer disease (AD) cerebral amyloid angiopathy (CAA) were studied as to morphology, extent, and association with mononuclear phagocyte system (MPS) cells using A beta, a-smooth muscle actin, and monocyte/macrophage marker (HLA-DR, CD68, CD11c, CD45) immunohistochemistry. The HCHWA-D/AD arterial/arteriolar media showed compact A beta deposits, first appearing at the media/adventitia junction, and concomitant smooth muscle loss. Only HCHWA-D CAA featured (a) severe involvement of larger arteries and (b) arterioles showing a single or double ring of radial A beta surrounding compact A beta. Radial A beta appeared to develop at the media/adventitia junction. Monocyte/macrophage marker-positive foci/cells co-localized with HCHWA-D arterial A beta. Focal HLA-DR/CD11c positivity was observed at the media/adventitia junction of AD/HCHWA-D arteries in the absence of local A beta, but not in controls. Monocyte/macrophage marker positivity co-localizing with radial A beta appeared continuous with perivascular cells and microglia clustering perivascularly. These results suggest that (a) MPS cells are topographically associated with HCHWA-D arterial A beta and radial arteriolar A beta, and (b) HLA-DR/CD11c immunoreactivity may appear at the media/adventitia junction prior to A beta. The latter finding and the assumed formation of radial A beta at the media/adventitia junction may relate to involvement of the abluminal basement membrane in CAA pathogenesis. The role of MPS cells in this process remains to be established.

Abstract
Cerebral amyloid-beta (A beta) angiopathy is the histopathological hallmark of hereditary cerebral hemorrhage with amyloidosis (Dutch) (HCHWA-D). A beta deposits are found mainly in the cerebral and cerebellar meningocortical blood vessels and as plaques throughout the cerebrocortical gray matter. A beta deposition in arteries and arterioles starts at the junction of media and adventitia and proceeds to involve the media causing degeneration of the vascular smooth muscle cells. Cerebrocortical arterioles often show one or two layers of radial A beta around a layer of homogenous A beta that replaces the media. Degenerating neurites, reactive astrocytes and microglial cells may surround cerebrocortical angiopathic arterioles and capillaries, probably in reaction to invasion of the perivascular neuropil by A beta fibrils. Furthermore, clusters of coarse extracellular matrix deposits may be found near A beta-laden cerebrocortical arterioles. The amyloid-associated proteins, cystatin C, and beta PP colocalize diffusely with Dutch vascular A beta, whereas HLA-DR immunoreactivity is found only in the periphery of the diseased vessel wall. The latter phenomenon may be related to the presence of perivascular cells. Angiopathic blood vessels frequently show structural changes. The relation of the described pathology to the development of hemorrhage, infarction and leukoencephalopathy needs further elucidation.

Abstract
BACKGROUND Hereditary cerebral hemorrhage with amyloidosis (Dutch) (HCHWA-D) and Alzheimer's disease (AD) have certain clinical and histopathologic features in common; both are characterized by cerebral amyloid beta deposits. Extracellular matrix (ECM) components have been demonstrated in plaques and in vascular amyloid of AD, suggesting a causative relation. EXPERIMENTAL DESIGN We studied the immunohistochemical expression of the ECM components collagen type I, III, and IV, heparan sulfate proteoglycan (HSPG), laminin, and fibronectin in cortical tissue of six HCHWA-D patients, two AD patients, and five controls. RESULTS The vasculature of control patients and the noncongophilic vessels in HCHWA-D and AD patients stained for all ECM components, with the exception of collagen type I in part of the capillaries. The media of normal larger vessels stained for collagen type I and III and fibronectin; a similar pattern was found in the vascular amyloid in HCHWA-D and AD patients. The plaques in HCHWA-D and AD reacted for HSPG and weakly for collagen III and IV and laminin. Furthermore, with the exception of anti-collagen type I, all anti-ECM Ab decorated coarse deposits clustered in the vicinity of thick-walled, amyloid-laden vessels in HCHWA-D patients; these deposits were not spatially related to amyloid beta-positive plaques. CONCLUSIONS This study demonstrates the presence of ECM components in the main pathologic features of HCHWA-D and as perivascular deposits. The observed distribution of matrix molecules is partly different from AD. The ECM may well be essential for the evolvement of the pathology of HCHWA-D.

Abstract
Accurate diagnosis of neuronal ceroid lipofuscinosis (NCL) is important for a correct prognosis of the disease and for genetic counseling. Up to now, no direct diagnostic test has been available for NCL. The clinical diagnosis is made on the basis of symptoms, neurophysiological, neuroradiological, and specific lipopigment pattern data. Recent advances in the genetics of NCL have enabled us to use polymorphic DNA markers linked to the CLN1 and CLN3 loci as a tool in the differential diagnosis of NCL. We have applied genetic analysis with polymorphic DNA markers flanking the CLN3 gene on chromosome 16 to two consanguineous families in which NCL occurs. In the first family, which is of Turkish extraction, two patients suffering from a protracted form of juvenile NCL previously had been diagnosed with juvenile NCL. Haplotypes from this family indicate that the patients and their healthy sibling are haplo-identical, suggesting that this protracted form of juvenile NCL is not linked to the CLN3 locus. In the second family, which is of Moroccan origin, one patient suffers from the early juvenile variant of NCL (Lake-Cavanagh). In this family, the patient and one of the healthy siblings have identical haplotypes, excluding linkage of early juvenile NCL to the CLN3 locus on 16p12.1-11.2. Therefore, these cases from different populations demonstrate that haplotype analysis can be used as an additional method to exclude the diagnosis of juvenile NCL.

Abstract
Plaque-like lesions and amyloid angiopathy were investigated in the frontal cerebral cortex of four patients with hereditary cerebral hemorrhage with amyloidosis (Dutch) (HCHWA-D), using immunohistochemical [antibodies to beta amyloid protein (A beta), beta protein precursor (beta PP), synaptophysin, ubiquitin (UBQ), cathepsin D, paired helical filaments (PHF) and glial fibrillary acidic protein (GFAP)], enzymehistochemical (acid phosphatase) and silver [methenamine silver (MS) and Palmgren] staining methods. Whereas A beta- and MS-positive diffuse plaques were found in all patients, only the three older patients showed neuritic or congophilic plaques, which were acid phosphatase and cathepsin D positive and contained beta PP-, synaptophysin- and UBQ-positive, but PHF-negative neurites. These plaques were surrounded by reactive astrocytes. Similar immuno- and enzymereactivity was found around congophilic blood vessels. Thus, apart from neuronal degeneration in a subset of plaque-like lesions and around blood vessels, this study shows an age-related morphology of the plaques in HCHWA-D, corresponding to that in Down's syndrome (DS), with the difference that neurofibrillary (NF) pathology is absent in HCHWA-D in contrast to DS. HCHWA-D may be considered as a model for congophilic plaque formation not associated with NF pathology.

Abstract
In hereditary cerebral hemorrhage with amyloidosis (Dutch) (HCHWA-D) beta/A4 amyloid deposition is found in meningocortical blood vessels and in diffuse plaques in the cerebral cortex. Diffuse plaques putatively represent early stages in the formation of senile plaques. Microglia are intimately associated with congophilic plaques in Alzheimer's disease (AD), but microglial involvement in diffuse plaque formation is controversial. Therefore, we studied the relationship between microglia and diffuse plaques in the cerebral cortex of four patients with HCHWA-D using a panel of macrophage/microglia markers (mAbs LCA, LeuM5, LeuM3, LN3, KP1, OKIa, CLB54, Mac1, Ki-M6, AMC30 and the lectin RCA-1). Eight AD patients, one demented Down's syndrome (DS) patient and four non-demented controls were included for comparison. In controls and HCHWA-D patients ramified or "resting" microglia formed a reticular array in cortical gray and subcortical white matter. Microglial cells in or near HCHWA-D diffuse plaques retained their normal regular spacing and ramified morphology. In AD/DS gray matter more microglial cells were stained than in controls and HCHWA-D patients. Intensely immunoreactive microglia with enlarged cell bodies and short, thick processes clustered in congophilic plaques. In contrast to the resting microglia, these "activated microglia" strongly expressed class II major histocompatibility complex antigen, HLA-DR, and were AMC30-immunoreactive. These findings support the view that microglia play a role in the formation of congophilic plaques but do not initiate diffuse plaque formation. Another finding in this study is the presence of strong monocyte/macrophage marker immunoreactivity in the wall of cortical congophilic blood vessels in HCHWA-D.

Abstract
Based on the recent discovery of co-localization of beta/A4 and cystatin C in cortical blood vessels of patients with cerebral hemorrhages due to sporadic amyloid angiopathy and patients with Alzheimer's disease we investigated the presence of these two proteins in the cortical blood vessels of patients suffering from hereditary cerebral hemorrhage with amyloidosis of the Dutch (n = 11) and the Icelandic (n = 2) type. The brains of three patients with sporadic cerebral amyloid angiopathy were also investigated. Blood vessels of the Dutch patients clearly showed immunostaining with beta/A4 as well as with cystatin C antibodies, whereas the blood vessels of Icelandic patients showed only staining with cystatin C. In one of the three sporadic amyloid angiopathy patients co-localization was shown as well. The co-localization of mutated beta/A4 with normal cystatin C in the Dutch patients suggests that cystatin C deposition occurs secondarily to beta/A4 deposition. This is probably also the case in sporadic amyloid angiopathy and Alzheimer's disease. Cystatin C deposition may play a role in the development of cerebral hemorrhages and leukoencephalopathy.

Abstract
We studied the presence and morphology of plaque-like lesions in the frontal cortex of six patients, aged 40 to 76 years, with hereditary cerebral hemorrhage with amyloidosis--Dutch type (HCHWA-D), using beta/A4 immuno-, silver, Congo red and thioflavin S staining. Two types of beta/A4 immunoreactive and Congo red-negative plaques were detected. The first type was composed of argyrophilic fibrous material in periodic acid-methenamine silver (PAM) and modified Bielschowsky staining and lacked silver-stained degenerating neurites. Therefore, this type of plaque has the same staining properties as the diffuse plaque described in Alzheimer's disease, Down's syndrome and nondemented elderly. The second type of plaque, occurring only in the three oldest patients and numerically increasing with age, consisted of a spherical non-argyrophilic area of granular texture with a rim of PAM-positive material. The PAM-positive fibrous material of both types of plaques was mingled with coarser and compact, irregular-shaped argyrophilic structures in the oldest patient. The described plaques did not show bright fluorescence with thioflavin S staining. These results indicate, that the morphology of plaques, encountered in HCHWA-D, is diverse and changes with age.

Abstract
Interphase cytogenetics is the application of nonradioactive in situ hybridization with chromosome-specific DNA probes to interphase nuclei. In this study, interphase cytogenetics was used to investigate 66 primary brain tumors (33 gliomas, 30 meningiomas, and three medulloblastomas) for numerical chromosomal aberrations of chromosomes 1, 6, 7, 10, 11, 17, 18, X, and Y. Of the 33 gliomas (17 astrocytomas grades II, III, and IV, five oligoastrocytomas, seven oligodendrogliomas, and four ependymal tumors), 22 were near diploid, while the remaining 11 showed a significant triploid or tetraploid component. The predominant specific aberrations in gliomas were an over-representation of chromosome 7 (13 cases) and an under-representation of chromosome 10 (16 cases). These changes were observed in grade III and grade IV astrocytomas, as well as in oligodendrogliomas. Other frequent numerical changes were a gain of chromosome 17 (six cases) and a loss of chromosome 18 (seven cases). This loss of chromosome 18 seemed relatively specific for gliomas with an oligodendroglial component (six cases). Only two of 33 gliomas displayed no genetic abnormality with the probes used. Seven patients with astrocytomas died of their brain tumor during the clinical follow-up period. Their astrocytomas did not show a different chromosomal constitution compared to the other gliomas. For the meningiomas, the probe panel was extended with a probe specific for chromosome 22. Loss of chromosome 22 was obvious in 21 of the 30 meningiomas, and was the sole abnormality in 11 meningiomas; in the other 10, this loss was associated with other chromosomal changes. Five of these tumors with additional aberrations were recurrent or atypical meningiomas. It is suggested that interphase cytogenetics can contribute to a better understanding of the biological behavior of these tumors and possibly result in better insights into prognosis and strategies for therapy.

Abstract
A case of duodenal somatostatinoma is described in a patient with Von Recklinghausen neurofibromatosis. The patient presented with exocrine pancreatic insufficiency, probably due to distal obstruction of the pancreatic duct by the tumor. Preoperative evaluation with calcium-pentagastrin and tolbutamide stimulation tests were nondiagnostic. At laparotomy, local excision of the tumor was performed. Pathological findings were compatible with duodenal somatostatinoma, causing pancreatic fibrosis. Somatostatin extracted from the tumor coeluted with the somatostatin-14 standard on high performance liquid chromatography (HPLC).

Abstract
Amyloid fibrils deposited in cerebral vessel walls in Dutch patients with hereditary cerebral hemorrhage with amyloidosis (HCHWA-D) are formed by polymerization of a 39-residue peptide similar to the beta-protein of Alzheimer's disease, Down syndrome, sporadic cerebral amyloid angiopathy and normal aging. Sequence analysis of genomic DNA in HCHWA-D patients demonstrated a point mutation, cytosine for guanine at position 1852 of the precursor beta-protein gene, which causes a single amino acid substitution (glutamine for glutamic acid) corresponding to position 22 of the amyloid protein. The normal allele was also present in these patients. To examine the expression of normal and variant beta-protein alleles in HCHWA-D we analyzed all the tryptic peptides obtained from several amyloid fractions from leptomeningeal vascular walls. Amino acid sequence of two peptides (T3a and T3b) with identical amino acid composition revealed that T3a had glutamine and T3b had glutamic acid at position 22. Thus both the normal and variant Alzheimer's beta-protein alleles are expressed in vascular amyloid in HCHWA-D and may be detected by tryptic peptide mapping. Moreover, we have developed a diagnostic assay for high risk populations and prenatal evaluation that is based on the existence of the mutation.
