    Tests for Haplotype-Trait Association table in PROC HAPLOTYPE may
    report incorrect chi-square and p-value

    Product: SAS/Genetics
    Component: HAPLOTYPE procedure
    Priority: ALERT

      For a particular haplotype, if the frequencies for either TRAIT1 or
      TRAIT2 and the COMBINED are zero, the Chi-square statistic reported in
      the "Tests for Haplotype-Trait Association" table and its associated
      p-value are incorrect. The correct Chi-square statistic in this case
      should be zero and the associated p-value should be one.

      There is no circumvention for this problem.
