Abstract: COL4A1 mutations have been associated with cerebral small-vessel disease, including perinatal intracerebral hemorrhage with consequent porencephaly, microbleeds, and lacunar strokes. Moreover, involvement of multiple organs and tissues like kidney, muscle, and large vessels have been reported. Three related patients with porencephaly bearing the G749S mutation in the COL4A1 gene and one healthy control belonging to the same family underwent skin biopsy. Tissue was examined by means of immunofluorescence microscopy and immunoreactivity for collagen type IV in skin basement membranes was tested. In subjects with COL4A1 mutation, we did not detect significant alterations of immunofluorescence patterns in basal membranes of different skin structures. Heterozygous COL4A1 G749S mutation is associated with a normal immunofluorescence pattern of skin basement membranes. Further studies are needed to clarify the role of possible functional abnormalities of the basement membranes in patients with this mutation. [ABSTRACT FROM AUTHOR]
