Reference #3 (Tagliavini F et al.): F198S
- INTRODUCTION (image)TOP (image)ABSTRACT (image)INTRODUCTION (image)EXPERIMENTAL PROCEDURES (image)RESULTS (image)DISCUSSION (image)REFERENCES Gerstmann-Sträussler-Scheinker disease (GSS)1 is an adult-onset neurodegenerative disorder (1 , 2 ) that is inherited as an autosomal dominant trait and segregates with variant genotypes resulting from the combination of a pathogenic mutation (P102L , P105L , A117V , F198S , D202N , Q212P , and Q217R) and a common polymorphism at codon 129 (Met / Val) in the prion protein (PrP) gene (PRNP) (3-9 )
- In previous studies we have determined the biochemical composition of amyloid fibrils extracted from brain tissue of patients with mutations F198S and Q217R in PRNP
- As previously observed in the Indiana kindred of GSS with F198S mutation (32 ) , the relative abundance of the low molecular weight fragment was not dependent upon the extent of amyloid burden
- Notably , the degree of protease resistance of this peptide was lower than that of other GSS mutant proteins since , unlike analogous fragments from patients with F198S and Q217R PrP variants , it was completely degraded in the presence of SDS
- Similar to previous studies on GSS F198S and Q217R , this fragment was derived from the mutant allele since only Val was found at position 117 and 129 (18 )
- The top diagram illustrates the polypeptide chain of mature human PrP with the octapeptide repeat region , the common Met / Val polymorphism at codon 129 , and the mutations A117V , F198S , and Q217R associated with GSS
- The first four PrP fragments correspond to amyloid peptides isolated from four GSS patients with F198S , Q217R , and A117V (present case) mutation

- Purified GSS amyloid is composed primarily of ~7-kd PrP peptides , whose N terminus corresponds to residues W81 and G88 to G90 in patients with the A117V mutation and to residue W81 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
- Conversely , in all patients with GSS F198S , an ~8-kd PrP sc fragment was isolated having the major N terminus start at residue G74
- 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
- 3 GSS is caused by mutations P102L , P105L , A117V , G131V , F198S , D202N , Q212P , and Q217R in PRNP
- 10 -13 , 14 , 15 Previous studies showed that the amyloid subunit in GSS F198S is a 7-kd peptide with an N terminus at residue G81.16 Similar studies in patients from one American and one Alsatian family with GSS A117V revealed that the 7-kd amyloid protein had a major N-terminal cleavage site at residue G81 and G88 to G90.17 -18 In addition , we have reported on the presence of PrP sc isoforms of ~27 to 29 , 18 to 19 , and 8 kd in brain extracts and microsomal fractions of patients from the Indiana kindred with GSS F198S
- To explore this possibility , we determined the N-terminal cleavage sites of the PrP fragments that accumulate in GSS A117V and GSS F198S

- The Clinical , Genetic , and Pathological Information for Five GSS A117V Patients and One Asymptomatic A117V Mutation Carrier ; and for Two GSS F198S Patients is Summarized Biochemical Assays Tissue was obtained from six subjects with PRNP A117V
- Tissue was obtained from the frontal cortex and cerebellum of a patient of the Indiana kindred (GSS F198S) heterozygous for the M / V polymorphism at codon 129
- Determination of the N-Terminal Cleavage Site of PrP Fragments in Patients with GSS A117V and GSS F198S To characterize the primary structure of the 7-kd PrP sc fragment , partially purified and PK-treated PrP obtained from the frontal cortex of patients with GSS A117V (ie , patients 1 to 5) was analyzed using Edman chemistry , after resolution of fragments by gel electrophoresis (see Materials and Methods)
- Patients with GSS F198S and GSS A117V accumulate PrP sc fragments that can be cleaved by PK to generate peptides of different mobility (ie , the small fragment is 7 kd in GSS A117V and 8 kd in GSS F198S) in gel electrophoresis
- To explore this possibility , we analyzed the 8-kd PrP sc fragment obtained from the frontal cortex of two patients with GSS F198S (Figure 5)(image)
- This indicates PK cleavage in the second PrP octarepeat region for GSS F198S , different from the PK cleavage site for GSS A117V
- To analyze the possibility that different PrP conformers might be present in different brain areas , we determined the N-terminal sequence of PrP sc purified from the caudate nucleus (an area with absent or small amounts of amyloid) , and the cerebellum (a region with abundant amyloid) in a homozygous 129 V patient with GSS F198S
- Studies on amyloid fractions have previously shown that patients with GSS F198S accumulate amyloid peptides of ~11 kd spanning residues 58 to 150
- 32 Further analysis showed that the smallest amyloid subunit in GSS F198S and GSS Q217R corresponds to a 7-kd fragment comprising residues W81 to Y150 and W81 to E146 , respectively.16 In addition , preliminary data on a patient of an American family with GSS A117V showed a similar fibrillogenic fragment with a ragged N terminus corresponding to W81 , G82 , and Q83 and the C terminus at E146.17 Thus , patients with these GSS variants may accumulate amyloid subunits of similar size and primary structure , despite the different genotypes and phenotypic presentations
- Therefore , to expand our studies we purified PrP sc from patients of the Indiana kindred with GSS F198S and determined the N-terminal cleavage site of the ~8-kd fragment isolated from areas with and without amyloid accumulation
- In view of the fact that the smallest amyloidogenic fragment has a mobility of ~7 kd and N terminus at W81 and PrPsc peptides of ~8 kd have an N terminus at G74 , we speculate that sequential proteolytic cleavage of a precursor PrP sc fragment generates fibrillogenic peptides in GSS F198S
- In conclusion , the data obtained in the GSS variants analyzed in this study demonstrate that N- and C-truncated PrP isoforms of different size and N-termini , accumulate in GSS A117V and GSS F198S
- The results show that octarepeats 3 and 4 are an integral part of the 8-kd peptide present in GSS F198S , but not in the 7-kd fragments detected in patients with GSS A117V

- Since the remaining GSS mutations (G131V , H178R , F198S , D202N , Q212P and Q217R) do not result in the creation of amino acid residues that are also conserved in Dpl , the hypothesis that GSS PRNP alleles result in PrPC molecules more Dpl-like than wt PrPC was rejected

- A GSS disease variant with mutation at codon 198 (F198S) has been studied in a large Indiana kindred
- In the present paper , we analyzed proteinase-K (PK)-resistant PrP in 7 patients with GSS F198S disease
- Our findings suggest that brain extracts from GSS F198S disease contain 3 prominent nonglycosylated PK-resistant PrP fragments forming a pattern not previously described in other prion diseases , which may in part explain the pathology of this GSS disease variant.

Reference #10 (Parchi P et al.): F198S
- In contrast , purified amyloid preparations from GSS affected subjects carrying the Y145STOP , F198S , A117V , or Q217R mutations were shown to contain PrP-res fragments of 11 and 7 kDa with ragged N and C termini (6 , 7 )
- Of interest , a 19-kDa PrP-res fragment , although supposedly not glycosylated , has been detected in GSS F198S (25 )
- The presence of a type 1 PrP-res in GSS P102L and of a type 2 PrP-res in GSS F198S would be consistent with the fact that , as shown for sporadic CJD , valine at codon 129 , which is invariably linked to the F198S mutation , favors the formation of PrP-res type 2 whereas methionine , which cosegregates with the P102L mutation , usually is associated with PrP-res type 1 (5 )
