Extra Alleles in Triple-Primed PCR
The objectives of this study were to determine the cause of these extra peaks; to identify whether these peaks represent an assay specific artifact, an underlying chromosome aneuploidy, or somatic mosaicism; and to ascertain their clinical relevance. The presence of an extra allele(s) was confirmed by a laboratory-developed PCR, with sequencing of the FMR1 5′ UTR or Southern blot for some samples.
