Localization of the gene (LAMA4) to chromosome 6q21 and isolation of a partial cDNA encoding a variant laminin A chain
1994
Abstract Laminin is a basement membrane glycoprotein composed of three nonidentical chains, A, B1, and B2. Variant chains such as merosin and S-laminin have been found in different tissues. We have isolated a cDNA encoding a novel laminin A variant that hybridizes to a 6.45-kb mRNA. Using amplification of genomic DNA and flow-sorted chromosomes we have assigned the gene (LAMA4) for this new laminin A variant to chromosome 6. Fluorescence in situ hybridization of a YAC clone further localized the gene to 6q21.
