Mission and programs · 2024
Mission
THE TRANSPLANTATION SOCIETY PROVIDES THE FOCUS FOR GLOBAL LEADERSHIP IN TRANSPLANTATION FOR THE DEVELOPMENT OF THE SCIENCE AND CLINICAL PRACTICE, SCIENTIFIC COMMUNICATION, CONTINUING EDUCATION AND GUIDANCE ON THE ETHICAL PRACTICE.
Activities or mission (Part I)
INTERNATIONAL LEADERSHIP IN THE SCIENCE, EDUCATION, ETHICS AND PRACTICE OF TRANSPLANTATION.
-
EVENTS HELD IN A VARIETY OF GLOBAL VENUES WHERE MEMBERS OF THE COMMUNITY ARE BROUGHT TOGETHER TO DISCUSS ADVANCEMENTS IN ORGAN TRANSPLANTATION. ORGAN TRANSPLANTATION IS A SUCCESSFUL THERAPY FOR END STAGE ORGAN FAILURE OF THE KIDNEY, LIVER, HEART, LUNG, PANCREAS AND INTESTINE. TRANSPLANTATION OF CELLS AND TISSUES ALSO TRANSFORMED THE THERAPEUTIC OPTIONS FOR PATIENTS WITH MALIGNANT HAEMATOLOGICAL DISEASE, EYE DISEASE AND ORTHOPAEDIC DISEASE, AND HAS THE POTENTIAL TO ALTER SIGNIFICANTLY THE THERAPEUTIC OPTIONS FOR PATIENTS WITH DIABETES AND A RANGE OF DISORDERS. THE ACCESS OF PATIENTS TO TRANSPLANTATION THERAPY VARIES WIDELY ACROSS THE GLOBE, PARTLY DETERMINED BY THE UNDERLYING LEVEL OF ECONOMIC DEVELOPMENT IN DIFFERENT STATES AND PARTLY DETERMINED BY OTHER FACTORS SUCH AS THE AVAILABILITY OF ORGAN, CELL AND TISSUE DONORS, OR THE SPECIALIZED PROVISION OF HEALTH SERVICES. THE ORGANIZATION HAS DETERMINED THAT IT WILL SEEK TO ADDRESS GLOBAL INEQUITIES IN TRANSPLANTATION THERAPY, IN ORDER TO FACILITATE APPROPRIATE ACCESS TO TRANSPLANTATION FOR ALL PATIENTS WHO WOULD BENEFIT.

As filed on the 2024 return. The filer continues this part on Schedule O, which is not shown here. A text marked withheld matched a screen for wording that may name a private individual, such as an honorific or "in memory of". Most of what it withholds names no one; it is withheld so that what does is never shown.

The first 25 listed. Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all. Showing the 10 most recent; the API carries the rest.

Auto-Revocation List
Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.
Publication 78
Listed as of 13 October 2026, under deductibility FORGN.
These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
