A mother and daughter are described with light and electron microscopic, and biochemical abnormalities of their connective tissue characteristic of both cutis laxa and the Ehlers-Danlos syndrome. The mother was clinically normal, while her 8-year-old daughter exhibited loose, wrinkled skin and other clinical features of cutis laxa, and also fragility, bruisability and hyper-extensibility of the skin and poor healing of wounds, leaving 'cigarette paper' scars, features characteristic of the Ehlers-Danlos syndrome. Light and electron microscopic studies of skin biopsy specimens and cultured skin fibroblasts from both individuals revealed reduced and distorted elastic fibres, a finding usually seen in cutis laxa. Electrophoretic studies of collagen excreted from cultured skin fibrobasts revealed in both individuals and alpha 2(I) chain with a molecular size smaller than usual. The father and elder daughter were normal by clinical, light and electron microscopic and electrophoretic studies. It was concluded from these findings that the mother and daughter represented a hitherto undescrbed disease of the connective tissue with dominant inheritance and variable expressivity.
