A disorder of cognition characterized by the tetrad of finger agnosia, dysgraphia, DYSCALCULIA, and right-left disorientation. The syndrome may be developmental or acquired. Acquired Gerstmann syndrome is associated with lesions in the dominant (usually left) PARIETAL LOBE which involve the angular gyrus or subjacent white matter.

Molecular determinants of the physicochemical properties of a critical prion protein region comprising residues 106-126. (1/61)

Prion diseases are marked by the cerebral accumulation of conformationally modified forms of the cellular prion protein (PrP(C)), known as PrP(res). The region comprising the residues 106-126 of human PrP seems to have a key role in this conformational conversion, because a synthetic peptide homologous with this sequence (PrP106-126) adopts different secondary structures in different environments. To investigate the molecular determinants of the physicochemical characteristics of PrP106-126, we synthesized a series of analogues including PrP106-126 H(D), PrP106-126 A and PrP106-126 K, with l-His-->d-His, His-->Ala and His-->Lys substitutions respectively at position 111, PrP106-126 NH(2) with amidation of the C-terminus, PrP106-126 V with an Ala-->Val substition at position 117, and PrP106-126 VNH(2) with an Ala-->Val substitution at position 117 and amidation of the C-terminus. The analysis of the secondary structure and aggregation properties of PrP106-126 and its analogues showed the following. (1) His(111) is central to the conformational changes of PrP peptides. (2) Amidation of the C-terminal Gly(126) yields a predominantly random coil structure, abolishes the molecular polymorphism and decreases the propensity of PrP106-126 to generate amyloid fibrils. (3) PrP106-126 V, carrying an Ala-->Val substitution at position 117, does not demonstrate a fibrillogenic ability superior to that of PrP106-126. However, the presence of Val at position 117 increases the aggregation properties of the amidated peptide. (4) Amyloid fibrils are not required for neurotoxicity because the effects of PrP106-126 NH(2) on primary neuronal cultures were similar to those of the wild-type sequence. Conversely, astroglial proliferation is related to the presence of amyloid fibrils, suggesting that astrogliosis in prion encephalopathies without amyloid deposits is a mediated effect rather than a direct effect of disease-specific PrP isoforms.  (+info)

Prominent psychiatric features and early onset in an inherited prion disease with a new insertional mutation in the prion protein gene. (2/61)

In five generations of the French M-E kindred, 11 members are now known to be or have been affected by a form of spongiform encephalopathy previously recorded as Gerstmann-Straussler-Scheinker disease. Mean age at onset was 28 years (range 21-34 years). In six instances, these patients were hospitalized in psychiatric institutions with various diagnoses, the most frequent being mania or mania-like symptoms. Dementia occurred progressively after a lengthy course. Histological studies showed atrophy of the cerebellar molecular layer, which contained kuru and multicentric plaques labelled with anti-prion protein antibodies. Spongiosis was not prominent and remained largely limited to the periphery of plaques; it was more marked in the thalamus, where plaques were scarce. A 192 base pair (bp) insert (eight extra repeats of 24 bp) in the octapeptide coding region of the prion protein gene (PRNP) within a codon-129 methionine allele was found in four symptomatic subjects. Early age at onset, the prominence of psychiatric symptoms and the long course of the disease are noticeable clinical features in this family with an inherited prion disease due to a new insertional mutation in PRNP.  (+info)

A single amino acid alteration (101L) introduced into murine PrP dramatically alters incubation time of transmissible spongiform encephalopathy. (3/61)

A mutation equivalent to P102L in the human PrP gene, associated with Gerstmann-Straussler syndrome (GSS), has been introduced into the murine PrP gene by gene targeting. Mice homozygous for this mutation (101LL) showed no spontaneous transmissible spongiform encephalopathy (TSE) disease, but had incubation times dramatically different from wild-type mice following inoculation with different TSE sources. Inoculation with GSS produced disease in 101LL mice in 288 days. Disease was transmitted from these mice to both wild-type (226 days) and 101LL mice (148 days). In contrast, 101LL mice infected with ME7 had prolonged incubation times (338 days) compared with wild-type mice (161 days). The 101L mutation does not, therefore, produce any spontaneous genetic disease in mice but significantly alters the incubation time of TSE infection. Additionally, a rapid TSE transmission was demonstrated despite extremely low levels of disease-associated PrP.  (+info)

A 7-kDa prion protein (PrP) fragment, an integral component of the PrP region required for infectivity, is the major amyloid protein in Gerstmann-Straussler-Scheinker disease A117V. (4/61)

Gerstmann-Straussler-Scheinker disease (GSS) is a cerebral amyloidosis associated with mutations in the prion protein (PrP) gene (PRNP). The aim of this study was to characterize amyloid peptides purified from brain tissue of a patient with the A117V mutation who was Met/Val heterozygous at codon 129, Val(129) being in coupling phase with mutant Val117. The major peptide extracted from amyloid fibrils was a approximately 7-kDa PrP fragment. Sequence analysis and mass spectrometry showed that this fragment had ragged N and C termini, starting mainly at Gly88 and Gly90 and ending with Arg148, Glu152, or Asn153. Only Val was present at positions 117 and 129, indicating that the amyloid protein originated from mutant PrP molecules. In addition to the approximately 7-kDa peptides, the amyloid fraction contained N- and C-terminal PrP fragments corresponding to residues 23-41, 191-205, and 217-228. Fibrillogenesis in vitro with synthetic peptides corresponding to PrP fragments extracted from brain tissue showed that peptide PrP-(85-148) readily assembled into amyloid fibrils. Peptide PrP-(191-205) also formed fibrillary structures although with different morphology, whereas peptides PrP-(23-41) and PrP-(217-228) did not. These findings suggest that the processing of mutant PrP isoforms associated with Gerstmann-Straussler-Scheinker disease may occur extracellularly. It is conceivable that full-length PrP and/or large PrP peptides are deposited in the extracellular compartment, partially degraded by proteases and further digested by tissue endopeptidases, originating a approximately 7-kDa protease-resistant core that is similar in patients with different mutations. Furthermore, the present data suggest that C-terminal fragments of PrP may participate in amyloid formation.  (+info)

Prion proteins with different conformations accumulate in Gerstmann-Straussler-Scheinker disease caused by A117V and F198S mutations. (5/61)

Gerstmann-Straussler-Scheinker disease (GSS) is characterized by the accumulation of proteinase K (PK)-resistant prion protein fragments (PrP(sc)) of approximately 7 to 15 kd in the brain. Purified GSS amyloid is composed primarily of approximately 7-kd PrP peptides, whose N terminus corresponds to residues W(81) and G(88) to G(90) in patients with the A117V mutation and to residue W(81) in patients with the F198S mutation. The aim of this study was to characterize PrP in brain extracts, microsomal preparations, and purified fractions from A117V patients and to determine the N terminus of PrP(sc) species in both GSS A117V and F198S. In all GSS A117V patients, the approximately 7-kd PrP(sc) fragment isolated from nondigested and PK-digested samples had the major N terminus at residue G(88) and G(90), respectively. Conversely, in all patients with GSS F198S, an approximately 8-kd PrP(sc) fragment was isolated having the major N terminus start at residue G(74). It is possible that a further degradation of this fragment generates the amyloid subunit starting at W(81). The finding that patients with GSS A117V and F198S accumulate PrP(sc) fragments of different size and N-terminal sequence, suggests that these mutations generate two distinct PrP conformers.  (+info)

Computational studies on prion proteins: effect of Ala(117)-->Val mutation. (6/61)

Molecular dynamics calculations demonstrated the conformational change in the prion protein due to Ala(117)-->Val mutation, which is related to Gerstmann-Straussler-Sheinker disease, one of the familial prion diseases. Three kinds of model structures of human and mouse prion proteins were examined: (model 1) nuclear magnetic resonance structures of human prion protein HuPrP (125-228) and mouse prion protein MoPrP (124-224), each having a globular domain consisting of three alpha-helices and an antiparallel beta-sheet; (model 2) extra peptides including Ala(117) (109-124 in HuPrP and 109-123 in MoPrP) plus the nuclear magnetic resonance structures of model 1; and (model 3) extra peptides including Val(117) (109-124 in HuPrP and 109-123 in MoPrP) plus the nuclear magnetic resonance structures of model 1. The results of molecular dynamics calculations indicated that the globular domains of models 1 and 2 were stable and that the extra peptide in model 2 tended to form a new alpha-helix. On the other hand, the globular domain of model 3 was unstable, and the beta-sheet region increased especially in HuPrP.  (+info)

Cell surface accumulation of a truncated transmembrane prion protein in Gerstmann-Straussler-Scheinker disease P102L. (7/61)

A familial prion disorder with a proline to leucine substitution at residue 102 of the prion protein (PrP(102L)) is typically associated with protease-resistant PrP fragments (PrP(Sc)) in the brain parenchyma that are infectious to recipient animals. When modeled in transgenic mice, a fatal neurodegenerative disease develops, but, unlike the human counterpart, PrP(Sc) is lacking and transmission to recipient animals is questionable. Alternate mice expressing a single copy of PrP(102L) (mouse PrP(101L)) do not develop spontaneous disease, but show dramatic susceptibility to PrP(Sc) isolates from different species. To understand these discrepant results, we studied the biogenesis of human PrP(102L) in a cell model. Here, we report that cells expressing PrP(102L) show decreased expression of the normal 18-kDa fragment on the plasma membrane. Instead, a 20-kDa fragment, probably derived from transmembrane PrP ((Ctm)PrP), accumulates on the cell surface. Because the 20-kDa fragment includes an amyloidogenic region of PrP that is disrupted in the 18-kDa form, increased surface expression of 20-kDa fragment may enhance the susceptibility of these cells to PrP(Sc) infection by providing an optimal substrate, or by amplifying the neurotoxic signal of PrP(Sc). Thus, altered susceptibility of PrP(101L) mice to exogenous PrP(Sc) may be mediated by the 20-kDa (Ctm)PrP fragment, rather than PrP(102L) per se.  (+info)

Unhampered prion neuroinvasion despite impaired fast axonal transport in transgenic mice overexpressing four-repeat tau. (8/61)

Transmissible spongiform encephalopathies often are caused by peripheral uptake of infectious prions, and the peripheral nervous system is involved in prion spread to the brain. Although the cellular prion protein is subjected to fast axonal transport, the mechanism of intranerval transport of infectious prions is unclear. Here we administered prions intranervally to transgenic mice overexpressing the four-repeat human tau protein, which exhibit defective fast axonal transport. These mice showed unaltered neuroinvasion, suggesting that transport mechanisms distinct from fast axonal transport effect prion neuroinvasion along peripheral nerves. Surprisingly, scrapie-sick tau transgenic mice accumulated intraneuronal deposits of hyperphosphorylated tau protein. The coincidence of tau and prion pathology resembled Gerstmann-Straussler-Scheinker syndrome. These findings identify tau pathology as a possible end stretch of prion-induced neurodegeneration.  (+info)

Gerstmann syndrome is a rare neurological disorder primarily characterized by the following four symptoms:
1. Finger agnosia - inability to identify or recognize fingers on their own hand, often struggling to distinguish between similar fingers like index and middle finger.
2. Left-right disorientation - difficulty determining left from right, sometimes affecting body awareness and spatial orientation.
3. Agraphia - an impairment in writing abilities, including difficulties with spelling, grammar, or composing coherent texts.
4. Acalculia - inability to perform basic arithmetic calculations or have trouble understanding numerical concepts.

These symptoms are typically associated with damage to the dominant parietal lobe, specifically within the angular gyrus region of the brain. Gerstmann syndrome is often observed in individuals who have experienced stroke, brain injury, or other forms of neurological damage. It's important to note that not all individuals with Gerstmann syndrome will exhibit all four symptoms, and some may experience additional cognitive or motor impairments depending on the extent of the brain damage.
