A Statistical Method for Observing Personal Diploid Methylomes and Transcriptomes with Single-Molecule Real-Time Sequencing

Abstract: We address the problem of observing personal diploid methylomes, CpG methylome pairs of homologous chromosomes that are distinguishable with respect to phased heterozygous variants (PHVs), which is challenging due to scarcity of PHVs in personal genomes. Single molecule real-time (SMRT) sequencing is promising as it outputs long reads with CpG methylation information, but a serious concern is whether reliable PHVs are available in erroneous SMRT reads with an error rate of ∼15%. To overcome the issue, we propo… Show more

“…Merker et al (74) used TGS to detect structural variation of the PRKAR1A gene, and thus diagnosed a case of Carney syndrome. Despite many advantages, TGS has a high error rate, SMRT can reach 15% (75). Although it is a random error that can be overcome by sequencing multiple times, it also faces problems in information storage and result interpretation and ethical issues related to genetic information.…”

“…In addition, when SMRT sequencing is performed on native non-amplified DNA molecules, it is possible to access several layers of additional information hidden in the kinetic signals emitted by the polymerases during the sequencing reaction [1]. This kinetic information has been used to detect epigenetic modifications at base pair resolution and even phasing of methylation signatures in diploid organisms, as presented in this special issue [5]. Several important discoveries have already been made from this kinetic information, such as the widespread presence of 6mA modifications in the human genome [6], a modification that was previously thought to only be present in bacterial genomes.…”
