I meant what Emacs shows when you type "C-h f define-abbrev RET".  It
says this:

  (define-abbrev TABLE NAME EXPANSION &optional HOOK &rest PROPS)

  Define an abbrev in TABLE named NAME, to expand to EXPANSION and call HOOK.
  NAME must be a string, and should be lower-case.
  EXPANSION should usually be a string.

  [...]

  PROPS is a property list.  The following properties are special:
  - ‘:count’: the value for the abbrev’s usage-count, which is incremented each
    time the abbrev is used (the default is zero).
  - ‘:system’: if non-nil, says that this is a "system" abbreviation
    which should not be saved in the user’s abbreviation file.
    Unless ‘:system’ is ‘force’, a system abbreviation will not
    overwrite a non-system abbreviation of the same name.
  - ‘:case-fixed’: non-nil means that abbreviations are looked up without
    case-folding, and the expansion is not capitalized/upcased.
  - ‘:enable-function’: a function of no argument which returns non-nil if the
    abbrev should be used for a particular call of ‘expand-abbrev’.

Note the ‘:case-fixed’ part: isn't that what you want?  If so, you
could modify your abbrev_defs file to make select abbrevs have fixed
letter-case.
