Genomic DNA from the aborted fetus was examined for mutations in laminin 5, a macromolecule involved in adhesion at the dermal\u2010epidermal junction, and a candidate protein in this condition. Polymerase chain reaction (PCR) amplification of exon 10 and parts of the flanking introns of the gene encoding the \u03b23 chain of laminin 5 (LAMB3) and subsequent analysis by agarose gel electrophoresis showed a more slowly migrating band in the affected fetus compared with the normal control. Nucleotide sequencing of the abnormal PCR product revealed a homozygous 77 bp duplication within the exon, resulting in a premature termination codon 250 bp downstream from the 3\u2032 end of the duplication. Maternal DNA was heterozygous for the mutant and wild\u2010type alleles. These findings illustrate the genetic basis of the skin disease in this case and also offer the prospects of a simple, rapid, and reliable first\u2010trimester DNA\u2010based prenatal, or even preimplantation, diagnostic test for future pregnancies in this family.<\/jats:p>","DOI":"10.1002\/pd.1970150710","type":"journal-article","created":{"date-parts":[[2007,3,4]],"date-time":"2007-03-04T11:13:38Z","timestamp":1173006818000},"page":"647-654","source":"Crossref","is-referenced-by-count":27,"title":["Genetic basis of lethal junctional epidermolysis bullosa in an affected fetus: Implications for prenatal diagnosis in one family"],"prefix":"10.1002","volume":"15","author":[{"given":"John A.","family":"McGrath","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James R.","family":"McMillan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.
