TP-PCR DNA chromatogram for normal, GZ, and PM subject from control and RSA cohort. a Homozygous sample with interrupted normal FMR1 alleles (29 CGG repeats). b Homozygous sample with normal FMR1 alleles (29 CGG repeats). One allele is interrupted by two AGG while other by 1 AGG. c Heterozygous sample with interrupted normal FMR1 alleles 29 and 40 repeats. d Heterozygous sample with interrupted normal allele of 29 and continuous GZ allele of 53 repeats (Pure CGG tract on second allele). e Heterozygous sample with interrupted normal allele of 30 CGG repeats and continuous PM allele of 99 CGG repeats (pure CGG tract on second allele). Note: blue vertical line shows edge of repeats in normal range and red vertical arrows depicts the position of AGG interruptions
