We describe a recurrent large expansion of a maternal allele with 36 CAG repeats (to 66 and 57 repeats, respectively, in two daughters) associated with onset of Huntington disease (HD) in the second and third decade in a family without history of HD. Our findings give evidence of a gonadal mosaicism in the unaffected mother. We hypothesize that large expansions also occur in the female germline and that a negative selection of oocytes with long repeats might explain the different instability behavior of the male and the female germlines.","tracks":[{"project":"NCBIDiseaseCorpus","denotations":[{"id":"T1","span":{"begin":70,"end":88},"obj":"SpecificDisease:D006816"},{"id":"T2","span":{"begin":186,"end":188},"obj":"Modifier:D006816"},{"id":"T3","span":{"begin":404,"end":422},"obj":"SpecificDisease:D006816"},{"id":"T4","span":{"begin":424,"end":426},"obj":"SpecificDisease:D006816"},{"id":"T5","span":{"begin":490,"end":492},"obj":"SpecificDisease:D006816"}],"attributes":[{"subj":"T1","pred":"source","obj":"NCBIDiseaseCorpus"},{"subj":"T2","pred":"source","obj":"NCBIDiseaseCorpus"},{"subj":"T3","pred":"source","obj":"NCBIDiseaseCorpus"},{"subj":"T4","pred":"source","obj":"NCBIDiseaseCorpus"},{"subj":"T5","pred":"source","obj":"NCBIDiseaseCorpus"}]},{"project":"PMID_GLOBAL","denotations":[{"id":"T1","span":{"begin":70,"end":88},"obj":"DiseaseOrPhenotypicFeature"},{"id":"T2","span":{"begin":186,"end":188},"obj":"DiseaseOrPhenotypicFeature"},{"id":"T3","span":{"begin":404,"end":422},"obj":"DiseaseOrPhenotypicFeature"},{"id":"T4","span":{"begin":424,"end":426},"obj":"DiseaseOrPhenotypicFeature"},{"id":"T5","span":{"begin":490,"end":492},"obj":"DiseaseOrPhenotypicFeature"}],"attributes":[{"id":"A1","pred":"mondo_id","subj":"T1","obj":"0007739"},{"id":"A2","pred":"mondo_id","subj":"T2","obj":"0007739"},{"id":"A3","pred":"mondo_id","subj":"T3","obj":"0007739"},{"id":"A4","pred":"mondo_id","subj":"T4","obj":"0007739"},{"id":"A5","pred":"mondo_id","subj":"T5","obj":"0007739"},{"subj":"T1","pred":"source","obj":"PMID_GLOBAL"},{"subj":"T2","pred":"source","obj":"PMID_GLOBAL"},{"subj":"T3","pred":"source","obj":"PMID_GLOBAL"},{"subj":"T4","pred":"source","obj":"PMID_GLOBAL"},{"subj":"T5","pred":"source","obj":"PMID_GLOBAL"}]},{"project":"NCBI-Disease-Train","denotations":[{"id":"T5096","span":{"begin":70,"end":88},"obj":"SpecificDisease"},{"id":"T5097","span":{"begin":186,"end":188},"obj":"Modifier"},{"id":"T5098","span":{"begin":404,"end":422},"obj":"SpecificDisease"},{"id":"T5099","span":{"begin":424,"end":426},"obj":"SpecificDisease"},{"id":"T5100","span":{"begin":490,"end":492},"obj":"SpecificDisease"}],"attributes":[{"id":"A5096","pred":"database_id","subj":"T5096","obj":"D006816"},{"id":"A5097","pred":"database_id","subj":"T5097","obj":"D006816"},{"id":"A5098","pred":"database_id","subj":"T5098","obj":"D006816"},{"id":"A5099","pred":"database_id","subj":"T5099","obj":"D006816"},{"id":"A5100","pred":"database_id","subj":"T5100","obj":"D006816"},{"subj":"T5096","pred":"source","obj":"NCBI-Disease-Train"},{"subj":"T5097","pred":"source","obj":"NCBI-Disease-Train"},{"subj":"T5098","pred":"source","obj":"NCBI-Disease-Train"},{"subj":"T5099","pred":"source","obj":"NCBI-Disease-Train"},{"subj":"T5100","pred":"source","obj":"NCBI-Disease-Train"}]},{"project":"NCBI-Disease-Corpus-All","denotations":[{"id":"T5096","span":{"begin":70,"end":88},"obj":"SpecificDisease"},{"id":"T5097","span":{"begin":186,"end":188},"obj":"Modifier"},{"id":"T5098","span":{"begin":404,"end":422},"obj":"SpecificDisease"},{"id":"T5099","span":{"begin":424,"end":426},"obj":"SpecificDisease"},{"id":"T5100","span":{"begin":490,"end":492},"obj":"SpecificDisease"}],"attributes":[{"id":"A5096","pred":"database_id","subj":"T5096","obj":"D006816"},{"id":"A5097","pred":"database_id","subj":"T5097","obj":"D006816"},{"id":"A5098","pred":"database_id","subj":"T5098","obj":"D006816"},{"id":"A5099","pred":"database_id","subj":"T5099","obj":"D006816"},{"id":"A5100","pred":"database_id","subj":"T5100","obj":"D006816"},{"subj":"T5096","pred":"source","obj":"NCBI-Disease-Corpus-All"},{"subj":"T5097","pred":"source","obj":"NCBI-Disease-Corpus-All"},{"subj":"T5098","pred":"source","obj":"NCBI-Disease-Corpus-All"},{"subj":"T5099","pred":"source","obj":"NCBI-Disease-Corpus-All"},{"subj":"T5100","pred":"source","obj":"NCBI-Disease-Corpus-All"}]},{"project":"NCBI-Disease-Corpus-2stage-All","denotations":[{"id":"T1","span":{"begin":70,"end":88},"obj":"SpecificDisease"},{"id":"T2","span":{"begin":404,"end":422},"obj":"SpecificDisease"},{"id":"T3","span":{"begin":424,"end":426},"obj":"SpecificDisease"},{"id":"T4","span":{"begin":490,"end":492},"obj":"SpecificDisease"}],"attributes":[{"subj":"T1","pred":"source","obj":"NCBI-Disease-Corpus-2stage-All"},{"subj":"T2","pred":"source","obj":"NCBI-Disease-Corpus-2stage-All"},{"subj":"T3","pred":"source","obj":"NCBI-Disease-Corpus-2stage-All"},{"subj":"T4","pred":"source","obj":"NCBI-Disease-Corpus-2stage-All"}]},{"project":"NCBI-Disease-Corpus-rezarta-All","denotations":[{"id":"T1","span":{"begin":70,"end":88},"obj":"SpecificDisease"},{"id":"T2","span":{"begin":186,"end":188},"obj":"Modifier"},{"id":"T3","span":{"begin":404,"end":422},"obj":"SpecificDisease"},{"id":"T4","span":{"begin":424,"end":426},"obj":"SpecificDisease"},{"id":"T5","span":{"begin":490,"end":492},"obj":"SpecificDisease"}],"attributes":[{"subj":"T1","pred":"source","obj":"NCBI-Disease-Corpus-rezarta-All"},{"subj":"T2","pred":"source","obj":"NCBI-Disease-Corpus-rezarta-All"},{"subj":"T3","p
