McLeod syndrome

Registered concept and code equivalence

Keep vr.tr.mcleod-syndrome authoritative while documenting whether external terms describe the syndrome, blood phenotype or a broader category.

1. Does the cited term denote XK-associated McLeod syndrome, the McLeod blood group phenotype or a broader neuroacanthocytosis category? boundary
2. Which issuing body, release and jurisdiction support each proposed ICD or SNOMED mapping? provenance

Evidence sufficiency and discordance

Record the diagnostic framework applied and unresolved discrepancies between molecular, serological and clinical observations.

1. Which published diagnostic guidance, version and assessor support the current diagnostic status? provenance
2. What evidence distinguishes this assessment from VPS13A disease, Huntington disease or an isolated blood group finding? boundary
3. Which discordant or missing results require specialist review before the assertion can change? action

Variant classification and test coverage

Capture the reported XK finding and the limits of the assay used.

1. What XK variant or deletion was reported, in what allelic state, and under which classification evidence and date? provenance
2. Did testing evaluate sequence variants and copy-number changes, and what relevant limitations remain? boundary

Relative status and neighbouring genes

Record family evidence, individual expression and any broader genomic finding without assigning diagnoses by relationship alone.

1. Which relatives have documented molecular, blood group or clinical evidence, and which remain unassessed? provenance
2. If a deletion extends beyond XK, which additional gene-associated conditions require separately linked assessments? boundary
3. What consent and genetics consultation are needed before arranging testing or communicating familial implications? action

McLeod phenotype evidence

Record Kx and Kell findings separately from acanthocyte counts and other haematological observations.

1. What methods and controls establish the Kx and Kell expression pattern, including any mixed cell populations? measurement
2. What acanthocyte and haemolysis results are available, with sampling dates, methods and laboratory interpretation? measurement

Documented transfusion requirements

Retain antibody history, prior reactions and the blood service's documented compatibility requirements.

1. Which antibodies, previous transfusions and reactions are documented in verified blood service records? provenance
2. Has transfusion medicine specified compatible components and a plan for obtaining them if needed? action
3. What changes or proposed procedures trigger reassessment of that plan? action

Movement, cognition, behaviour and seizures

Maintain dated assessments with attribution, severity and uncertainty for each manifestation.

1. Which movement, cognitive, psychiatric or seizure manifestations have been assessed, and when did each begin? measurement
2. Which observations support attribution to McLeod syndrome rather than medication effects or another condition? boundary

Neuromuscular burden and functional change

Relate examination and investigation results to changes in mobility, swallowing and daily activities.

1. What do strength, reflex, creatine kinase and any electrophysiological assessments show, using dated methods and reference ranges? measurement
2. What documented change in mobility, swallowing or daily function warrants rehabilitation or additional specialist assessment? action

Cardiomyopathy and rhythm status

Link symptoms and cardiac investigations to a current specialist assessment.

1. What do dated ECG, rhythm monitoring and cardiac imaging show, including ventricular function where measured? measurement
2. Which symptoms or findings require escalation under the treating team's documented cardiac plan? action

Individualised surveillance and management

Associate each proposed review or intervention with its indication, responsible clinician and evidence basis.

1. Which neurological, cardiac, haematological and functional reviews are due under the current specialist plan? action
2. Which source and publication date support each surveillance interval or management recommendation? provenance
3. What outcomes and adverse effects will determine whether an intervention should be reassessed? measurement
