Multiple microcrystal deposition within a family.
Abstract
A family is described in which four members in three generations showed evidence of crystal deposition disease: two developed calcium pyrophosphate dihydrate (CPPD) crystal deposition, one calcific periarthritis, and one mixed crystal deposition disease (gout + chondrocalcinosis). This previously undescribed observation supports a possible role for nonspecific heritable connective tissue factors in predisposing to crystal deposition.
