Measure of Insulinemia rate during an orally induced hyperglycemia
Measure of Insulinemia rate in order to compare the association between the profile of insulin secretion (Insulinemia , C-peptide and glycaemia) during an orally induced hyperglycemia and the known diagnosis of lipodystrophy linked to a mutation of the LMNA (FPLD2) gene.
Measure of C-peptide rate during an orally induced hyperglycemia
Measure of C-peptide rate in order to compare the association between the profile of insulin secretion (Insulinemia, C-peptide and glycaemia) during an orally induced hyperglycemia and the known diagnosis of lipodystrophy linked to a mutation of the LMNA (FPLD2) gene.
Measure of glycaemia rate during an orally induced hyperglycemia
Measure of glycaemia rate in order to compare the association between the profile of insulin secretion (Insulinemia, C-peptide and glycaemia) during an orally induced hyperglycemia and the known diagnosis of lipodystrophy linked to a mutation of the LMNA (FPLD2) gene.
Research of mutation of the LMNA (FPLD2) gene
Research of mutation of the LMNA (FPLD2) gene in order to compare the association between the profile of insulin secretion (Insulinemia, C-peptide and glycaemia) during an orally induced hyperglycemia and the known diagnosis of lipodystrophy linked to a mutation of the LMNA (FPLD2) gene.
