Premature Stop Codon in <i>MMP20</i> Causing Amelogenesis Imperfecta
1 Jan 2008
Abstract excerpt
Proteolytic enzymes are necessary for the mineralization of dental enamel during development, and mutations in the kallikrein 4 (KLK4) and enamelysin (MMP20) genes cause autosomal-recessive amelogenesis imperfecta (ARAI). So far, only one KLK4 and two MMP20 mutations have been reported. We have identified an ARAI-causing point mutation (c.102G>A, g.102G>A, and p.W34X) in exon 1 of MMP20 in a proband with...
