    Notes: Abstract The term congenital dyserythropoietic anaemia (CDA) designates a group of rare but well defined erythrocytic disorders. Type I is defined by macrocytosis and megaloblastic changes of the bone marrow cells. Two unrelated children with CDA are described with associated defects: absence of nails and short or absent phalanges, polysyndactyly of the fourth metacarpal. One of them had also areas of depigmentation. Conclusion The association of congential dyserythropoietic anaemia with morphological defects of hands and feet is suggested to constitute a new syndrome caused by a single morphogenetic gene.

    Notes: Abstract The Smith-Lemli-Opitz syndrome (SLO) is an autosomal recessive disorder characterized by dysmorphic facial features with abnormal limbs and genitalia. Two forms have been recognized based on clinical course and severity: the classical SLO (type I) and the lethal acrodysgenital syndrome (type II). Type I SLO has been recently ascribed to a defect in cholesterol synthesis. Taking advantage of a series of seven patients including five type I and two type II SLO, we describe micrognathia, severe microcephaly, major ante and post natal growth retardation and feeding difficulties as consistent features in the disease. In addition, we give support to the presence of abnormal cholesterol levels in the lethal acrodysgenital syndrome but find no correlation between plasma sterol levels and the clinical severity of the disease.

Conclusion. The identification of the same biochemical defect in both types of Smith-Lemli-Opitz Syndrome suggests that despite major discrepancies in clinical course and severity, type I and type II SLO are probably allelic disorders.

    Notes: Abstract Based on the study of three unrelated families, we report what we believe to be the first in vivo evidence of muscle ATPase deficiency in individuals carrying the neurogenic weakness, ataxia and retinitis pigmentosa (NARP) syndrome mtDNA mutation (T8993G). Since plasma citrulline was consistently low in 4/5 patients, we suggest that the NARP mutation caused complex V deficiency in the small intestine as well, thus reducing the availability of mitochondrial ATP required for citrulline synthesis. Conclusion We suggest giving consideration to hypocitrullinaemia as a hallmark of the neurogenic weakness, ataxia and retinitis pigmentosa syndrome mutation and more generally of impaired oxidative phosphorylation in the small intestine in vivo.

    Notes: Abstract A 25-month-old boy, born to consanguineous parents, had progressive spastic tetraplegia, and increased signal of the white matter on cerebral T2-weighted magnetic resonance imaging indicative of diffuse leukodystrophy. Elevated blood and cerebrospinal fluid lactate levels pointed to a respiratory chain defect. Cytochrome-c oxidase deficiency was demonstrated in cultured skin fibroblasts and skeletal muscle. This report extends the phenotype of COX deficiency in infancy. Systematic study of blood and CSF lactate should be carried out in every infant with leukodystrophy.
