Brief Summary:

This study is an observational (ie, noninterventional), longitudinal, multicenter, global registry for patients with pyruvate kinase (PK) deficiency, a rare nonspherocytic hemolytic anemia.

This Registry will be open for enrollment for 7 years and all enrolled participants will be followed prospectively for a minimum of 2 years, and up to 9 years.

Data will be collected from participating Registry Physicians, participants, and, where appropriate, parents/guardians who have provided informed consent or assent (where relevant) and authorization pursuant to applicable laws and regulations.

Data should include demographic, clinical, and treatment data; and other data of relevance to the management of patients with PK deficiency. Annual chart review and data entry are expected in order to enhance longitudinal understanding of PK deficiency; however, no specific protocol schedule of assessment is required by this Registry protocol.

PKD Diagnosed
Participants diagnosed with PK deficiency by the presence of 2 or more PKLR gene mutations as well as clinical features.

Primary Outcome Measures :
  1. Clinical Course of PK Deficiency [ Time Frame: 9 years ]
    To develop an understanding of the longitudinal clinical implications of PK deficiency, including disease natural history, treatments and outcomes, and variability in clinical care and disease burden.

Secondary Outcome Measures :
  1. Severity of Disease [ Time Frame: 9 years ]
    To understand the prevalence, incidence, and severity of complications associated with PK deficiency.

  2. Disease Impact on Pregnancy [ Time Frame: 9 years ]
    To evaluate pregnancy outcomes.

  3. Clinical Management Assistance [ Time Frame: 9 years ]
    To provide a source of longitudinal data to assist physicians with clinical management of individual patients.

  4. Global Repository [ Time Frame: 9 years ]
    To act as a global repository for potential data from other properly consented PK deficiency-related studies to support aggregate and comparative analyses.

Other Outcome Measures:
  1. Genetic [ Time Frame: 9 years ]
    To examine a possible correlation between PKLR genotype and PK deficiency clinical phenotype.

Layout table for eligibility information
Ages Eligible for Study:   Child, Adult, Older Adult
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Patients will be recruited or referred by physicians who treat hemolytic anemias at approximately 60 sites in approximately 20 countries.

Inclusion Criteria:

  • Participants of all ages with a confirmed diagnosis of PK deficiency via genetic testing are eligible to enroll;
  • Participants will be considered for enrollment on the basis of clinical features consistent with PK deficiency together with the presence of 2 or more PKLR gene mutations. For novel or indeterminate PKLR gene mutations, participants will be deemed eligible if, in the opinion of the investigator, the reported PKLR gene mutations are sufficient to support a diagnosis of PK deficiency;
  • The participant or the parent/guardian of the participant must be willing and able to give written informed consent and/or assent. E-consent or remote consent may be utilized where permissible as applicable if country regulations and site policies allow.
