Early-onset Parkinson disease v0.130 FXTAS Bryony Thompson STR: FXTAS was added
STR: FXTAS was added to Early-onset Parkinson disease. Sources: Literature
Mode of inheritance for STR: FXTAS was set to X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males)
Publications for STR: FXTAS were set to 27340021; 28176767; 20301558; 23765048; 25227148; 11445641
Phenotypes for STR: FXTAS were set to Fragile X tremor/ataxia syndrome MIM#300623
Review for STR: FXTAS was set to GREEN
STR: FXTAS was marked as clinically relevant
Added comment: Parkinsonism is a common feature of FXTAS, which is associated with the premutation.
HGVS nomenclature - NM_002024.5:c.-129_-127CGG[X]
RNA-mediated toxicity may result in the FXTAS phenotype, whereas loss of function through methylation silencing of FMR1 is associated with the FXS phenotype.
Intermediate (grey zone, inconclusive, borderline): ~45 to ~54 repeats
Premutation - risk of FXTAS: ~55 to ~200 repeats
Full mutation - fragile X syndrome (FXS): >200 repeats

Early-onset Parkinson disease v0.129 FMR1 Bryony Thompson Phenotypes for gene: FMR1 were changed from Fragile X tremor/ataxia syndrome MIM#300623; Fragile X syndrome MIM#300624 to Fragile X tremor/ataxia syndrome MIM#300623
Early-onset Parkinson disease v0.128 FMR1 Bryony Thompson Publications for gene: FMR1 were set to 27340021; 28176767
Early-onset Parkinson disease v0.127 FMR1 Bryony Thompson changed review comment from: Parkinsonism can be a relatively common feature of the condition. The major cause of the condition is 5'UTR repeat expansion, but at least 6 pathogenic intragenic SNV or small indels have been reported in affected males.; to: Parkinsonism can be a relatively common feature of FXTAS, which is caused by 5'UTR repeat expansion.

Early-onset Parkinson disease v0.127 FMR1 Bryony Thompson Classified gene: FMR1 as No list
Early-onset Parkinson disease v0.127 FMR1 Bryony Thompson Added comment: Comment on list classification: Parkinsonism is a feature of FXTAS and is not reported in cases with intragenic variants, which have the FXS phenotype. Added as an STR.
