Blood m.3243A>G levels in a cohort of mitochondrial disease patients

The median time between first and last measurement was 2.5 years (IQR = 4.35, range = 0.01 – 15.20), the median age at first measurement was 36.25 years (IQR = 20.58, range = 15.60 – 72.50) and at last measurement was 40.25 years (IQR = 21.00, range = 19.80 – 78.80).   </p> <p>Variables are as follows:</p> <p>ID: Anonymised patient number</p> <p>age: Age at first m.3243A>G measurement</p> <p>age2: Age at last m.3243A>G measurement</p> <p>het: First m.3243A>G measurement; this is uncorrected for age and is expressed as a %.</p> <p>het2: Last m.3243A>G measurement; this is uncorrected for age and is expressed as a %.</p> <p><br></p> <p>2. mother_child_3243_data.csv</p> <p>This file contains blood m.3243A>G level measurements originally published in PIckett, Blain et al. 2019 (doi: 10.1056/NEJMc1808565).</p> <p>Data are from 245 mother-child pairs from 141 unique mothers.</p> <p>Variables are as follows:</p> <p>mother_id = anonymised unique ID for each mother</p> <p>b_mother = Mother's blood m.3243A>G measurement; this is uncorrected for age and is expressed as a %.</p> <p>b_child = Child's blood m.3243A>G measurement; this is uncorrected for age and is expressed as a %.</p> <p>age_mother = age at which mother's m.3243A>G measurement was taken</p> <p>age_child = age at which child's m.3243A>G measurement was taken</p> <p>proband_child = 1 if the child is a proband, 0 if not</p> <p>proband_mother = 1 if the mother is a proband, 0 if not</p> <p><br></p> <p>Further details of the protocol for collection of these data are available within:</p> <p>Grady, Pickett et al. 2018 (doi: 10.15252/emmm.201708262) and</p> <p>PIckett, Blain et al. 2019 (doi: 10.1056/NEJMc1808565).</p> <p><br></p> <p>If you use any of this data respository in any published work, please cite using:</p> <p><br></p> <p>Pickett, SJ, Shiau Ng, Y, Wilson, I, Alston, C, Blakely, E, Turnbull, D, Gorman, G, Taylor, RW, Mcfarland, R  </p> <p>"Blood m.3243A>G levels in a cohort of mitochondrial disease patients"  DOI:10.25405/data.ncl.20286219 </p> <p><br></p>
