DNP 810 Week 2: case report part 1 guide
Part one asks for two things only, and the commonest error is writing the whole case report now — leaving parts two to four with nothing left to say.

Part one is disease and testing, and nothing else yet
Choose the case first and choose it for the whole series, because this is part one of four and the same patient carries through to the end. The brief names Duchenne muscular dystrophy, Huntington's disease, Down syndrome, sickle cell anaemia and BRCA variants as examples, and any of those works because each has a well-described molecular basis, published epidemiology and an established testing pathway — which is exactly what parts one and two need. The constraint that matters is that the case must be real: from your own practice, your experience or your own family. Simulated cases are excluded, and the reason is that this assignment earns practice immersion hours, which cannot be claimed against invented work. The condition also has to sustain three further parts, so check before committing that its inheritance pattern and its treatment options both have enough published detail to write about later.
Then hold the scope. Part one wants the disease described with its prevalence and incidence, and the laboratory testing that is possible. That is all, and resisting the urge to write the inheritance analysis now is what leaves part two something to do. Be precise about the two epidemiological terms, since they are routinely confused: incidence is new cases in a period, prevalence is existing cases at a point, and for a chronic genetic condition they diverge sharply — a condition with low incidence can have substantial prevalence because affected people live for decades. Give the figures with their population and their source. On testing, describe the sequence rather than naming one investigation: what screens, what confirms, what the turnaround is, and what a negative result does and does not exclude. Carrier and prenatal options belong here too where they exist. Say what the turnaround is too, because a family waiting on a result experiences the delay as part of the diagnosis.
Likely learning objectives
Inferred from the brief — check these against your own rubric.
- 01Select a genetic condition that can sustain a four-part case report.
- 02Distinguish incidence from prevalence and report both correctly.
- 03Describe a diagnostic testing pathway rather than a single test.
- 04Hold the scope of one part of a staged assignment.
Read the full question
Review every instruction before using the planning guidance that follows.
Turn the brief into deliverables
- 01A real case, not a simulated one.
- 02A description of the disease.
- 03Prevalence and incidence figures with their populations and sources.
- 04The laboratory testing pathway, including what a negative result excludes.
- 05The Practice Hours Completion Statement after the references.
Case, disease, epidemiology, then the laboratory
The case
Introduce the real patient or family and the condition involved.
The disease
Describe the condition, its molecular basis and its clinical course.
Prevalence and incidence
Report both figures with their populations and sources.
Laboratory testing
Set out the testing sequence and what each step establishes.
Prevalence and incidence are different numbers
Recommended databases
- MedlinePlus Genetics
- National Human Genome Research Institute
- StatPearls
- PubMed Central
Search sequence
- 1.Confirm the diagnostic pathway from a clinical source before describing it.
- 2.Find prevalence and incidence figures separately, and note their populations.
- 3.Check whether carrier or prenatal testing exists for your condition.
- 4.Read what Topics 1 and 2 covered, since the paper is meant to incorporate them.
Reference shortlist
These are authoritative starting points, not a ready-made bibliography. A qualified reviewer must confirm that each source fits the assignment and supports the claim beside which it is cited.
Nothing here is cleared for citation until you have read it.

Review before submission
Common mistakes
- Writing the whole case report in part one.
- Using incidence and prevalence interchangeably.
- Quoting a figure without saying which population it describes.
- Naming one test rather than describing a pathway.
- Using a simulated case, which cannot earn practice hours.
Submission checklist
- Is the case real and will it sustain three more parts?
- Are incidence and prevalence distinguished and sourced?
- Does the testing section describe a sequence?
- Have you said what a negative result does not exclude?
- Is the practice hours statement present?
