PMCID: PMC3370276 abstract: We performed hypothesis-free linkage analysis and exome sequencing in a family with two siblings who had neuronal ceroid lipofuscinosis (NCL). Two linkage peaks with maximum LOD scores of 3.07 and 2.97 were found on chromosomes 7 and 17, respectively. Unexpectedly, we found these siblings to be homozygous for a c.813_816del (p.Thr272Serfs∗10) mutation in the progranulin gene (GRN, granulin precursor) in the latter peak. Heterozygous mutations in GRN are a major cause of frontotemporal lobar degeneration with TDP-43 inclusions (FTLD-TDP), the second most common early-onset dementia. Reexamination of progranulin-deficient mice revealed rectilinear profiles typical of NCL. The age-at-onset and neuropathology of FTLD-TDP and NCL are markedly different. Our findings reveal an unanticipated link between a rare and a common neurological disorder and illustrate pleiotropic effects of a mutation in the heterozygous or homozygous states. date: 2012-06-08 official_url: http://dx.doi.org/10.1016/j.ajhg.2012.04.021 oa_status: green language: eng primo: open primo_central: open_green article_type_text: Journal Article, Research Support, Non-U.S. Gov't verified: verified_manual elements_source: PubMed elements_id: 411809 doi: 10.1016/j.ajhg.2012.04.021 pii: S0002-9297(12)00254-6 lyricists_name: Mole, Sara lyricists_id: SEMOL61 full_text_status: public publication: The American Journal of Human Genetics volume: 90 number: 6 pagerange: 1102 - 1107 event_location: United States issn: 0002-9297 citation: Smith, KR; Damiano, J; Franceschetti, S; Carpenter, S; Canafoglia, L; Morbin, M; Rossi, G; ...
