FUNCTION: This gene encodes the alpha-2 subunit of type V collagen, one of the low abundance fibrillar collagens that gets incorporated into growing fibrils with type I collagen. The encoded protein, in association with alpha-1 and/or alpha-3 subunits, forms homo- or heterotrimeric type V procollagen that undergoes proteolytic processing. Mice lacking the encoded protein die in utero. Transgenic mice that produce a structurally abnormal form of the encoded protein survive poorly and exhibit skin fragility, skeletal abnormalities and alterations in the collagen fiber organization.

PHENOTYPE: Homozygous mutation of this gene results in perinatal lethality. Mutant animals exhibit reduced body weight, reduced bone growth rate, thin, fragile skin, variable degrees of lordosis and kyphosis, abnormal localization of hair follicles in the dermis, and thinned stroma of the cornea.
