Long-term follow-up of R403WMYH7 and R92WTNNT2 HCM families: mutations determine left ventricular dimensions but not wall thickness during disease progression.

Person = numbers refer to pedigree identification numbers; see Fig. 1 for pedigrees 103, 137 and 139, references 10 for pedigree 100 and 109, and reference 11 for pedigree 106. Ped = pedigree, M = male, F = female, 1 = baseline measurement, 2 = final measurement, yrs = years, IVS = end-diastolic interventricular septal thickness, PW = end-diastolic posterior wall thickness, LAD = left atrial diameter, LVEDD = left ventricular end-diastolic diameter, LVESD = left ventricular end-systolic diameter, EF = ejection fraction, NA = not available.
