Diagram illustrating results of fragile X analysis by PCR
Bands are drawn to simulate the way they actually appear.
Examples given are:
Male, normal: 29 repeats
Female, normal: 30 and 28 repeats
Female, grey zone: 50 repeats (grey zone) and 19 repeats (normal allele)
Female, premutation: 84 repeats (premutation) and 22 repeats (normal allele)
Male, premutation: 76 repeats
Male, full mutation: No normal band. The full mutation must be confirmed by Southern blot analysis.
