MFN2 and lipomatosis: According to the Online Mendelian Inheritance in Man (OMIM) database, six forms follow an autosomal dominant inheritance pattern (types 2 [LMNA], 3 [PPARG], 4 [PLIN1], 7 [CAV1]), AKT2-related FPLD, and ADRA2-related FPLD), whereas three follow an autosomal recessive inheritance pattern (types 5 [CIDEC], 6 [LIPE], and FPLD with MFN2 associated lipomatosis) [32].
