- We report two brothers with glycerol kinase deficiency (GKD). The older brother had serious clinical symptoms, mental and growth retardation, abnormal skeleton, spontaneous fractures and premature loss of abnormal teeth. He and his mother had low serum phosphate levels. He had elevated serum and urine glycerol levels and GKD was found in cultured fibroblasts. Prenatal diagnosis was performed in the second pregnancy. Glycerol kinase activity was considered normal in a chorionic villus sample of the foetus. After birth, it was found that the boy had elevated serum and urine glycerol levels. Enzymatic analysis in cultured fibroblasts revealed that this boy also had GKD, in spite of having no expression of the disease. Chromosomal analyses in the parents and both boys were normal. Major rearrangements or deletions were not detected in molecular studies of DNA from the two brothers. The hybridisation pattern was normal and no allelic loss was observed.

- Analysis of the connexin32 gene in patients with X-linked Charcot-Marie-Tooth disease shows mutations distributed throughout the molecule, with all domains affected except the fourth transmembrane domain and the distal carboxy terminus. Sequence analysis of DNA from 19 unrelated patients detected six novel mutations and three previously reported mutations. Identification of additional mutations extends the distribution of connexin32 mutations in X-linked Charcot-Marie-Tooth disease and shows that specific mutations recur in additional families.
