Because FPLD is an extreme example of genetically disturbed adipocyte differentiation, it is possible that common variation in LMNA is associated with obesity-related phenotypes.

Although FPLD mutations are predominantly localized in exon 8 of LMNA, the finding of a novel mutation at codon 584, together with the R582H heterozygous substitution recently described, confirms that the C-terminal region specific to the lamin A isoform is a second susceptibility region for mutations in FPLD.

Twenty-three different mutations of LMNA have so far been shown to cause autosomal-dominant Emery-Dreifuss muscular dystrophy (EDMD2), three mutations were reported to cause limb-girdle muscular dystrophy (LGMD1B), eight mutations are known to result in dilated cardiomyopathy (CMD1A), and seven mutations were reported to cause familial partial lipodystrophy (FPL).

It is still not at all clear how defects in these nuclear membrane proteins are related to the phenotype, even less clear that LMNA mutations can also be associated with familial dilated cardiomyopathy with no weakness, and even familial partial lipodystrophy with diabetes mellitus and coronary heart disease!

By contrast, lamin A and C molecules harboring a point mutation (R482W), which gives rise to a dominant form of familial partial lipodystrophy, behave in a manner that is indistinguishable from wild-type lamins A and C, at least with respect to targeting and assembly within the nuclear lamina.

One form of lipodystrophy, namely Dunnigan-type familial partial lipodystrophy (FPLD) was shown to result from mutations in the LMNA gene, which encodes nuclear lamins A and C. Although the relationship between the mutations in the nuclear envelope and insulin resistance is unclear at present, these findings might eventually be shown to have relevance for the common insulin resistance syndrome and for drug-associated lipodystrophies.
