Fig. 2. Comparison of D4Z4 repeat array size distribution of FSHD1 alleles in unrelated FSHD1 patients from India (this study) and in other populations based on previous publications [19–21].
Plot titles show number of FSHD alleles (in parentheses), and mean repeat array size. X axes: repeat array size in units (U) and Y axes: D4Z4 repeat array size. For non-European populations, European data is underlaid in outline (Y axis not to scale) to illustrate the latter’s relatively broad allelic range.
