          Interleukin Genetics Reports First Quarter Financial Results

    WALTHAM, Mass.--(BUSINESS WIRE)--May 9, 2006--

    - Commercial Launch of New Genetic Tests Begins -

    Interleukin Genetics, Inc. (AMEX: ILI) today reported financial
results for the quarter ended March 31, 2006. The company generated
revenue of $232,000 and a net loss of $1.6 million or $0.07 per basic
and diluted common share for the quarter. Interleukin Genetics'
reported revenues resulted almost entirely from the processing of
genetic tests for cardiovascular health and general nutrition.
    "Interleukin Genetics has made the successful transition to
commercial operations in the first quarter through the introduction of
two new genetic assessment tests," said Ken Kornman, Interleukin
Genetics' CEO. "Our objective is to now build on this key operational
milestone by focusing our attention on expanding our genetic testing
services and business development initiatives, as well as our
development pipeline. In addition, we are committed to increasing the
scope of applications utilizing the Company's intellectual property,
and we look forward to reporting on our progress going forward."

    Operating Highlights for the quarter ended March 31, 2006:

    --  The Company commenced sales of two new genetic tests for
        personal wellness assessment - the interleukin-1 test for
        cardiovascular health and the general nutrition test.

    --  Interleukin Genetics began operations in its specially
        designed and constructed genetic testing laboratory. The
        laboratory is registered under CLIA, the Clinical Laboratory
        Improvements Amendments, with the Division of the Centers for
        Medicare and Medicaid Services that regulates laboratory
        testing in the United States. Samples were first processed in
        February, 2006.

    --  The Company initiated a new study in China utilizing its
        proprietary interleukin-1 technology to evaluate potential
        population-specific genetic links to myocardial infarction at
        an early age and expects to enroll approximately 1,300
        subjects. A similar study that is ongoing in Korea will enroll
        approximately 750 subjects.

    --  Interleukin Genetics announced executive management changes as
        it focuses on executing its commercial strategy and expanding
        development programs. Ken Kornman, the company's founder and
        Chief Scientific Officer, assumed the additional role of CEO,
        replacing Phil Reilly who will remain Chairman of the Board of
        Directors. Gregg Mayer joined the company as Chief Business
        Officer and is driving business operations and strategy.
        Interleukin Genetics is actively seeking new opportunities and
        strategic alliances that capitalize on its proprietary
        interleukin-1 technology for the development of genetic tests
        and therapeutic products.

    Financial Results:

    Revenue for the three months ended March 31, 2006 was $232,000
compared to $7,000 in the same period of 2005. The increase was
largely due to the amounts received for processing the cardiovascular
health and general nutrition genetic tests that are sold by the
company's strategic partner, Alticor. Cost of revenue, which includes
fixed overhead costs associated with laboratory operations, was
$198,000 for the three months ended March 31, 2006, resulting in a
gross profit of $34,000. For fiscal year 2006, the company is
currently projecting a gross profit margin of 40-45% from these
genetic tests.
    Research and development expenses were $729,000 for the quarter
ended March 31, 2006 compared to $684,000 for the quarter ended March
31, 2005, an increase of approximately 7%. These expenses include
research and development expenses funded by Alticor under research and
development agreements for the development of new tests. This increase
was the result of new accounting rules that required the recording of
stock-based compensation of approximately $74,000.
    General and administrative expenses were $765,000 for the three
months ended March 31, 2006 compared to $704,000 during the same
period in the prior year, an increase of approximately 9%. This
increase was the result of new accounting rules that required the
recording of stock-based compensation of approximately $69,000.
    The company reported a net loss of $1.6 million, or $0.07 per
basic and diluted common share, in the first quarter of 2006 compared
to a net loss of $1.5 million, or $0.06 per basic and diluted common
share, in the first quarter of 2005.
    On March 31, 2006, the company reported cash and cash equivalents
of $2.9 million compared to $3.4 million of cash and cash equivalents
on December 31, 2005.
