We report on a C-to-T transition in exon 6 of the PLP gene in a male with Pelizaeus-Merzbacher disease/X-linked spastic paraplegia. The transition changes a glutamine at amino acid residue 233 to a termination codon. This premature stop codon probably results in a truncated protein that is not funct

โฆ Synopsis
A transition C506T was found in exon 4 of the proteolipid protein gene of a boy with spastic paraplegia. This mutation resulted in the substitution of phenylalanine for serine 169, which is in the third transmembrane domain of the proteolipid protein molecule. The mutation apparently arose de novo, as it was absent from his mother. Am.

## Pelizaeus -Merzbacher disease/X-linked spastic paraplegia (PMD/SPG2) comprises a spectrum of diseases that range from severe to quite mild. The reasons for the variation in severity are not obvious, but suggested explanations include the extent of disruption of the transmembrane portion of the
Chondrodysplasia punctata (CP) is a heterogeneous group of bone dysplasias that are characterized by abnormal calcium deposition in areas of enchondral bone formation. The existence of an X-linked recessive form of chondrodysplasia punctata (CDPX) has been recognized in patients who are nullisomic f
X-linked hydrocephalus is caused by mutations in the gene for neural cell adhesion molecule L1 (L1CAM). In this report, we describe identification of a mutation in an isolated case of hydrocephalus with adducted thumbs. Tracing the origin of the mutation within the family showed a degree of somatic
We report linkage analysis in a new family with nonspecific X-linked mental retardation, using 27 polymorphic markers covering the entire X-chromosome. We could assign the underlying disease gene, denoted MRX65, to the pericentromeric region, with flanking markers DXS573 in Xp11.3 and DXS990 in Xq21
We have reinvestigated a large kindred identified over 25 years ago segregating for a form of pure autosomal dominant hereditary spastic paraplegia (HSP). We have examined additional relatives in order to refine the clinical and genetic characteristics of this disorder, and performed an analysis to
