EASTBIO PhD: The Hidden Role of Acrocentric Short Arms in Genome Instability

EASTBIO PhD: The Hidden Role of Acrocentric Short Arms in Genome Instability

Research Focus and Fit

Do repeat-rich chromosome regions omitted from conventional references conceal somatic rearrangements in myeloma, and can those rearrangements affect regulation at partner loci? This Edinburgh IGC doctorate combines repeat-aware cancer genomics, longitudinal analysis and multiomic interpretation to address those questions. Colin Semple and Aneta Mikulasova provide complementary computational and cancer-genomics expertise. The challenge is to distinguish a genuine structural change from a mapping artefact, then assess what the change means without treating co-occurrence as causation.

The four-year EASTBIO competition has an explicit Edinburgh international tuition top-up arrangement, so overseas applicants have a credible complete-fee-and-maintenance route without already holding an award. The immediate action is to contact IGC about qualification equivalence and the precise 2027 registration route, while arranging the application and both references for 16 November 2026. That date has no published clock or timezone in the IGC notice. IGC exact current acrocentric-short-arm project IGC current EASTBIO recruitment and international funding

Research Problem and Doctoral Work

Acrocentric chromosomes 13, 14, 15, 21 and 22 have repeat-rich short arms. Incomplete reference representation makes reads from these regions difficult to place reliably. The T2T reference represents 66.1 Mb across these short arms, opening a new analytical opportunity; it does not eliminate variation between patients and the reference. The project focuses on somatic changes in myeloma rather than assuming that findings about inherited variation establish cancer mechanisms. T2T 2022 foundational human genome original

The advertised starting observations are rearrangements in 6 of 23 CoMMpass genomes, a chromosome-14 p–q inversion associated with more than 500 kb of methylation remodelling and a new chromatin domain in one PDX, and a 14p beta-satellite region assigned a super-enhancer state by ChromHMM in another. The last annotation contrasts with the usual H3K9me3-rich heterochromatin context. These are preliminary observations: the small discovery set does not establish population prevalence, an associated inversion does not demonstrate causation, and a computational state label does not independently prove enhancer function.

The doctoral work has three linked scales. About 1,000 CoMMpass cases are proposed for describing rearrangement frequency, sequence context and architecture; 65 longitudinally sequenced cases address whether rearrangements remain stable or become more complex during clonal evolution. Multiomic data from 13 PDXs are proposed for studying partner-locus effects through methylation, histone marks, RNA-seq and Micro-C. These are distinct tasks and sample sets, not interchangeable replication cohorts. Training covers structural-variant analysis, repeat-aware T2T analysis and epigenomic/three-dimensional-genome integration. The advertised counts do not independently establish access permissions, usable samples or guaranteed outputs. IGC exact current acrocentric-short-arm project

A defensible thesis would make the uncertainty visible: distinguish genuine rearrangements from ambiguous repeat mapping, separate within-patient evolution from cross-cohort technical differences, and test whether the same samples support a proposed link between architecture, chromatin and expression. Reference choice, tumour purity, subclonal mixtures and measurement coverage are potential analytical confounders. These are questions for study design, not evidence that the present pipeline has already solved them. A robust negative result about an apparent regulatory association could be as informative as a positive one. The field's momentum comes from improved reference representation and multiomic inference; clinical prediction or treatment selection remains beyond the demonstrated project evidence.

School, Programme and Field Context

The confirmed host is the Institute of Genetics and Cancer in Edinburgh's School of Genetics and Cancer, within the College of Medicine and Veterinary Medicine. The official project names IGC supervisors and the University is the degree-awarding institution; EASTBIO is the funding/training partnership. Neither the network nor PDX collaborators imply a joint degree or a separate research-institute doctorate. IGC offers a substantial postgraduate community, research facilities and scientific activities, but advertised availability does not allocate secure computing, specialist staff or instrument time to this student. IGC exact current acrocentric-short-arm project IGC graduate research and training environment EASTBIO cohort and training framework

A related official HGU catalogue entry is Genetics and Molecular Medicine, programme 838. The accessible specification explicitly concerns 2026 entry and gives a generic three-year full-time PhD. It does not independently establish this project's exact 2027 title, registration code, start date or four-year registration arrangements. The project itself advertises a four-year funded opportunity. These specifications require reconciliation by IGC rather than replacing the award duration with the generic course length or assuming another school’s registration arrangements apply. Related HGU programme 838 historical 2026 entry specification

IGC's structured student-supervisor discussion is held at the beginning and annually to clarify expectations. It is useful evidence of a support framework, not a promise of weekly meetings or a complete personal progression calendar. EASTBIO adds cohort and interdisciplinary development; the individual training plan, placement arrangements and thesis milestones should be confirmed. Edinburgh reports fourth UK research power in REF 2021 and nearly 90% world-leading or internationally excellent research. That is a historical institutional measure, not a current IGC subject ranking or a ranking of either supervisor. The strongest project-specific signal is the combination of repeat genomics, cancer epigenomics and computational infrastructure.

Supervisor and Lab Assessment

Semple's official university profile identifies him as Professor and head of the IGC Bioinformatics Analysis Core. His group studies computational genomics, genome organisation and regulatory variation. Mikulasova's official group page identifies her as a Research Fellow working on genomic and epigenomic instability in myeloma, with particular interest in structural variation in heterochromatin. The exact project calls Semple primary supervisor and Mikulasova co-supervisor. Contacts are colin.semple@ed.ac.uk and amikulas@ed.ac.uk. Their complementary remit is well matched to the question, while the balance of day-to-day cancer expertise, computational mentoring and senior supervision still needs discussion.

Three genuine supervisor-coauthored originals illustrate that fit, with unequal reading depth:

• Mikulasova et al., Genome Research 2022. The study integrates chromatin and rearrangement evidence in lymphoid malignancies to examine epigenomic relocation of broad H3K4me3 domains after super-enhancer hijacking. It supports the team's expertise in regulatory consequences of structural change. The recorded reading covered the complete original abstract and selected primary-indexed Results; the full Methods, supplementary material and raw data were not audited. Its findings do not prove the proposed 14p beta-satellite mechanism. The December 2021 online version and 2022 issue are one study. Mikulasova et al. 2022 H3K4me3 broad-domain original
• Ewing et al., Nature Communications 2025. This Semple-coauthored study analyses structural diversity and survival across 324 ovarian tumours from five cohorts. The recorded reading covered the complete abstract, cohort design, and selected Results and Discussion. Distinct structural trajectories and imperfect event classification matter when interpreting hotspots and prognosis. Cross-cohort survival associations do not validate a myeloma biomarker, and the earlier preprint is not another independent study. Ewing et al. 2025 ovarian-cancer structural trajectories original
• Kaiser and Semple, BMC Biology 2025 model CTCF-anchored loop dynamics in human meiosis using single-cell-informed inference. The recorded reading covered the complete abstract and selected Results and Discussion. The authors discuss missing direct cell-type CTCF measurements, cohesin effects and unmodelled larger-scale changes; loop changes also do not strongly predict expression changes. This provides relevant three-dimensional-genome modelling expertise, while germline meiosis remains a different context from somatic myeloma. Kaiser and Semple 2025 meiotic chromatin-loop original

Together, the three studies concern chromatin rearrangement in lymphoid malignancy, ovarian-cancer structural evolution and meiotic three-dimensional genome modelling; none independently validates this project’s proposed myeloma mechanism. The lab/core environment supports interdisciplinary analysis, but previously awarded grants and access to a large research community do not guarantee personal allocations. The project notice lists four Semple students, two expected to finish in December 2026; that is a dated workload indicator, not proof of future availability or a meeting schedule.

Funding, Application, and Living Cost

The IGC project notice advertises a four-year EASTBIO studentship. UKRI covers Home-level fees and maintenance; Edinburgh explicitly covers the international tuition difference. The EASTBIO FAQ states that successful international candidates are not charged that top-up, while limiting international recruits to 30% of annual intake. This cap is neither a China ban, a project-specific seat count nor an individual's admission probability. Personal 2027 stipend rates, payment dates and the written award's continuation conditions remain unconfirmed. IGC current EASTBIO recruitment and international funding EASTBIO current international fee-waiver and funding FAQ

The project-specific route is completed EASTBIO application form plus PDF academic transcripts emailed to student-admin@igc.ed.ac.uk. Two referees must send EASTBIO template references to the same address by 16 November 2026. Network rules permit one project application and require academic or professional references from people other than the proposed project supervisors. The EASTBIO application process requires the anonymous EDI response identifier. This is not the Biology school's Euclid route, and no midday cutoff or two-week reference grace period is established for IGC. The network timeline supplies a general 1 October start, but the individual registration date should be confirmed.

For scale, the 2026/27 UKRI minimum is £21,805 and Edinburgh's 2026/27 single-postgraduate living estimate is £18,504 for 52 weeks, including an average £978 a month for accommodation and utilities. Their £3,301 annual difference is a same-year reference calculation, not a promised 2027 surplus. Housing choice, inflation, deposits, travel and dependants can change the budget materially. Research grants and training resources are not personal living income. Edinburgh 2026/27 postgraduate living budget UKRI current stipend reference

The cited Student visa page lists an application fee of £558 and the student healthcare surcharge is £776 per visa year; visa length and part-year rules affect the total. The EASTBIO FAQ excludes visa and healthcare costs. These are dated planning figures, not locked 2027 prices. Admission, CAS, financial/English evidence and any offer-specific ATAS requirement remain separate from winning funding.

Applicant Fit and Preparation

The strongest preparation is in computational genomics, bioinformatics, statistical genetics or a related quantitative life-science field, with evidence of careful data interpretation. The network normally requires a 2:1 undergraduate degree or international equivalent and does not require a Master's. Someone below that undergraduate threshold but with a Master's or substantial relevant professional experience may still be considered for assessment; this is a discretionary route, not automatic eligibility. The advert offers training and does not specify every named multiomic technique as a pre-entry requirement. EASTBIO current 2027 application rules EASTBIO current international fee-waiver and funding FAQ

There is a positive Chinese-qualification route through Edinburgh's recognised-university equivalence assessment, alongside the worldwide funding policy. The China page's 80–85% table is explicitly for taught postgraduate study and two named MScR programmes, so it should not be converted into this PhD's percentage cutoff. A Chinese Master's also does not itself settle undergraduate equivalence or an English exemption. IGC should confirm both against the actual 2027 registration. China postgraduate qualification equivalencies

The related HGU 2026 catalogue lists IELTS 6.5 with 6.0 components and dated TOEFL alternatives, but this review has not independently verified those as this project's 2027 conditions. Request the current threshold, accepted test version and exemption criteria before booking a test. The network permits an application before the certificate is available, though evidence may be required before a formal offer. Related HGU programme 838 historical 2026 entry specification EASTBIO current international fee-waiver and funding FAQ

Preparation can show a previous analytical question, data quality checks, validation boundaries and a reproducible explanation of what a result does and does not establish. Familiarity with repeat mapping, structural variation and multiomic interpretation would help; these are analyst-suggested preparation areas, not an extra official prerequisite list. Experience limited to uncritical pipeline output, or interest primarily in clinical intervention, would leave substantial gaps relative to this project.

Career Relevance

Transferable skills could support academic cancer genomics, bioinformatics cores and research-data roles.

Next Actions and Questions to Verify

Before applying: obtain IGC confirmation of 2027 degree title/code, start and registration length, Chinese qualification assessment, current English conditions and deadline timezone. Follow the IGC email instructions and arrange both template references by the deadline. The published international fee-gap arrangement makes the route relevant to overseas applicants, while selection remains competitive.

At interview: establish which cohort permissions and data are already secured; usable short- and long-read coverage; the initial thesis question; how ambiguous repeat mapping and PDX context will be handled; and the division of meetings, computational support and scientific supervision. Ask how the project will distinguish a ChromHMM annotation or a neo-domain association from a demonstrated regulatory effect, without assuming causality from the preliminary examples.

Before accepting: check the complete tuition top-up, four-year maintenance calendar, stipend uprating, research/placement support, computing and storage provision, visa costs and any continuation liability in writing. Scientific readiness and supervision detail deserve scrutiny; neither the absence of a personal award today nor an unknown future rate by itself makes this internationally funded competition inaccessible.

Evidence and Sources

The IGC notice gives a 16 November 2026 deadline but no closing time or time zone, and current availability remains unconfirmed. The 2026 HGU specification does not establish this project’s 2027 registration or English conditions. Findings from the cited papers remain specific to their study designs and do not replace functional validation of the proposed myeloma question.
