Abstract
Somatic mosaicism is a frequent phenomenon in Mendelian disorders that exhibit a high proportion of new mutations. However, mutant alleles present at low frequency may escape detection. We have previously shown that denaturing high-performance liquid chromatography (DHPLC) at the recommended melt temperature can detect TSC1 and TSC2 mutations in tuberous sclerosis patients with low-level somatic mosaicism, even when direct sequencing cannot identify the causative lesion. Here, we report the use of temperature modulation in DHPLC analysis to facilitate the robust detection of a mosaic mutation, N1643K, in the presence of a coexisting constitutional polymorphism.
