Lamellar ichthyosis (LI) is an autosomal recessive keratinization disorder of the skin. Genetic heterogeneity has been shown for the disease and there is evidence for the involvement of the transglutaminase 1 (TGM1) gene on chromosome 14q11. We have previously identi®ed chromosome 14q11 haplotypes a

✦ Synopsis
Autosomal recessive lamellar ichthyosis (LI) is a rare inherited disease of cornification of the skin. Recently, the gene responsible for type I LI has been identified and mutations have been described. The identification of mutations in families at risk for LI allows a precise and rapid prenatal diagnosis. A family with a previously unreported mutation is described and a prenatal diagnosis based on a simple polymerase chain reaction (PCR) approach is outlined. The molecular diagnosis was confirmed on post-mortem examination of the skin. 1997

MJD is the most frequent dominant ataxia and an incapacitating disorder. Onset is most frequently during the reproductive years, and genetic counselling is its only means of prevention. The causative mutation-an expansion of a (CAG) n on chromosome 14q32.1-can now be directly detected. We now report
