Mitochondrial DNA sequences of familial (maternal vs. non-maternal) ALS cases in whole blood, platelets and white blood cells


ABSTRACT: To address the question of whether mtDNA mutations might play a role in familiar ALS (fALS), mtDNA was isolated from whole blood (WB), white blood cells (WBC) and platelets (PLT) from fALS patients and the mitochondrial genome was analyzed using a mtDNA resequencing array (Affymetrix MitoChip v2.0) that allows detection of low-level heteroplasmy in addition to the conventional homoplasmic or heteroplasmic mutations. We distinguished between fALS cases with a prominent maternal (mat) inheritance pattern and fALS cases that do not point to a maternal inheritance pattern (non-mat). As additional controls we compared our results to healthy age and sex matched individuals without any known neurodegenerative background. With this we are aiming to get a deeper insight into a possible role of mtDNA alterations acting as a disease modifier in a subgroup of ALS patients presenting with a maternal transmission of the disease.
