         VISIBLE GENETICS REPORTS ON TRUGENE HIV-1 GENOTYPING KIT STATUS



TORONTO, CANADA (June 28, 2000): Visible Genetics Inc. (VGI, Nasdaq: VGIN)
reported today on the status of the US FDA submission for its TRUGENE HIV-1
Genotyping Kit.

VGI has been working closely with the FDA to develop testing processes and trial
parameters appropriate for the TRUGENE HIV-1 Genotyping Kit, which we believe
would be the first ever sequencing-based diagnostic test submitted to the FDA
for approval. In 1999, in consultation with the FDA, the Company began
conducting a series of trials involving both human HIV plasma samples and
laboratory-constructed molecular infectious clones (MICs).

As of today, VGI has successfully completed and analyzed the results of the
performance and analytic trials, including all trials involving human HIV plasma
samples. The Company believes that the results of these tests confirm that the
TRUGENE HIV-1 Genotyping Kit functions as intended and at the level of
performance necessary to gain FDA clearance. VGI is currently performing one
final study involving laboratory-constructed MICs rather than samples drawn from
HIV infected patients. The Company has reviewed its progress to date with the
FDA and expects to complete the one remaining study in the coming weeks and
submit its application to the FDA in the third quarter of this year. The
remaining study using the MIC panels does not require additional clinical trials
or patient enrollment.

"I am very pleased with the performance of our TRUGENE HIV-1 Genotyping Kit on
the extensive set of clinical HIV samples studied in conjunction with preparing
our FDA submission," said Richard T. Daly, President and CEO of VGI. "While the
laboratory procedures associated with using MICs to







construct experimental HIV samples have taken slightly longer than initially
anticipated, we believe that the TRUGENE HIV-1 Genotyping Kit is on track to
become the first sequencing-based diagnostic test to be allowed for marketing in
the US."


Visible Genetics Inc. is a leader in the emerging field of pharmacogenomics,
which uses genetic information in the identification and analysis of genes to
improve patient care and reduce healthcare costs. VGI manufactures and markets
high performance automated DNA sequencing systems and complete kits for the
analysis of genes linked to disease. The Company's OpenGene(TM) system employs
patented CLIP(TM) technology - a single-step, bi-directional sequencing method
that significantly reduces the time and cost involved in identifying clinically
relevant genetic information.
