## Abstract We report a consanguineous Lebanese family where six individuals had disproportionate short stature, short limbs, and bilateral genu varum that were apparent after 2 years of age. Major radiographic features in infancy included flared, cupped, and ragged metaphyses of all long bones, de

β¦ Synopsis
Ehlers-Danlos syndrome (EDS) type I is a generalized connective tissue disorder, the major manifestations of which are soft, velvety hyperextensible skin and moderately severe joint hypermobility. The gene defect or defects causing EDS type I have not yet been defined, but previous observations suggested that the syndrome may be caused by mutations in the genes for type-I collagen (COL1A1 and COL1A2) or type-III collagen (COL3A1). Here, we performed linkage studies for these three genes in large Azerbaijanian family with EDS type I. Three polymorphisms in the COL3A1 gene, two in the COL1A1 gene, and one in the COL1A2 gene were tested using the polymerase chain reaction. The data obtained excluded linkage of any of the three genes to EDS type I in the family.

Pneumonitis followed by lung fibrosis is a frequent complication of radiation therapy of chest tumors. A hallmark of these fibrotic lesions is the excessive production and accumulation of extracellular matrix proteins such as type I collagen. In addition to TGF-beta1, IL-4 has been recognized as a p
