Fig. 2: FAME1 repeat expansion analysis with ExpansionHunter, exSTRa and STRetch.

Repeat expansion analysis output for the TTTTA repeat expansion (a–c) and the TTTCA repeat insertion (d–f) in SAMD12 associated with FAME1. Two affected individuals (A-II-2, A-III-2) and one unaffected individual (A-III-1) from Family A and two affected individuals (B-II-5, B-II-7) from Family B are shown in colour, while 69 control individuals without FAME are shown in light grey for comparison. a and d show smaller and larger allele sizes predicted by ExpansionHunter with a small amount of noise jitter to distinguish samples that share the same genotype. b and e show empirical cumulative distribution functions (CDFs) of the number of bases matching the repeat motif created from the exSTRa scores. c and f show histograms of negative log base-10 transformed false discovery rate adjusted p values returned by STRetch (padj). The red dashed vertical line represents padj = 0.05. TREDPARSE and GangSTR results are shown in Fig. S1.
