The specific mutation position within the LMNA sequence can partially predict the phenotype, but the underlying mechanisms for the development of these different phenotypes are still unclear. To investigate whether different DNA methylation patterns contribute to the development of different phenotypes caused by LMNA mutations, we analyzed a panel of ten candidate genes related to fat metabolism, aging, and a tendency to different methylation patterns: CSPG2, ESR1, IGF1R, IGFR2, LMNA, MLH1, RANBP1, RARB, ZMPSTE24, and TGFBR1. We studied two independent families each comprising three individuals affected by familial partial lipodistrophy type 2 (FPLD2). Affected members in each family carried two different mutations of the LMNA gene (R482L and R471G respectively). In addition, we analyzed four progeria patients (2\u00d7LMNA\/C G608G, 1\u00d7LMNA\/C S143F, and 1\u00d7ZMPSTE24 IVS9-Ex10) and seven healthy adults. The gene encoding retinoic acid receptor B (RARB) showed a higher methylation in all six patients with FPLD2 when compared with the progeria patients with other LMNA mutations as well as the healthy controls (P&amp;lt;0.05). All other investigated genes showed no difference in the methylation patterns between the groups. A drug-induced inhibition of the retinol pathway is discussed as the key pathway for developing HAART-associated lipodystrophy and our data support a possible role of the retinol pathway in the development of lipodystrophy phenotypes.<\/jats:p>","DOI":"10.1677\/jme-07-0035","type":"journal-article","created":{"date-parts":[[2007,6,7]],"date-time":"2007-06-07T10:54:52Z","timestamp":1181213692000},"page":"663-671","update-policy":"https:\/\/doi.org\/10.1530\/crossmarkpolicy-6","source":"Crossref","is-referenced-by-count":3,"title":["The retinol acid receptor B gene is hypermethylated in patients with familial partial lipodystrophy"],"prefix":"10.1530","volume":"38","author":[{"given":"Rene","family":"Cortese","sequence":"first","affiliation":[{"name":"Epigenomics AG Berlin, Kleine Pra\u0308sidentenstr. 1, 10178 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Florian","family":"Eckhardt","sequence":"additional","affiliation":[{"name":"Epigenomics AG Berlin, Kleine Pra\u0308sidentenstr. 1, 10178 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marianne","family":"Volleth","sequence":"additional","affiliation":[{"name":"Institute of Human Genetics, Otto-von-Guericke University, Leipziger Str. 44, 39120 Magdeburg, Germany 1"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manfred","family":"Wehnert","sequence":"additional","affiliation":[{"name":"Institute for Human Genetics, Ernst-Moritz-Arndt University, Fleischmannstrasse 42\/44, 17489 Greifswald, Germany 2"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Uwe","family":"Koelsch","sequence":"additional","affiliation":[{"name":"University Children\u2019s Hospital, Department of Perinatology: Gerhard-Hauptmann-Str. 35, 39108 Magdeburg, Germany 3"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Wieacker","sequence":"additional","affiliation":[{"name":"Institute of Human Genetics, Otto-von-Guericke University, Leipziger Str. 44, 39120 Magdeburg, Germany 1"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Brune","sequence":"additional","affiliation":[{"name":"University Children\u2019s Hospital, Department of Perinatology: Gerhard-Hauptmann-Str. 35, 39108 Magdeburg, Germany 3"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"416","published-online":{"date-parts":[[2007,4,18]]},"reference":[{"key":"2026070808165549300_AHUJA-ETAL-2001","unstructured":"Ahuja\n              N\n            \n          , Toyota M, Bronner MP & Brentnall TA 2001 Accelerated age-related CpG island methylation in ulcerative colitis Issa JP.
