A screening for submicroscopic rearrangements was performed in 111 patients with idiopathic mental retardation (MR) using fluorescence in situ hybridization (FISH) probes from the subtelomeric regions of all chromosome arms. Ten cryptic rearrangements were found (9%): five de novo deletions; one unbalanced de novo translocation; three unbalanced inherited(More)
Autosomal dominant polycystic kidney disease (ADPKD), caused by mutation in PKD1 or PKD2, is usually an adult-onset disorder but can rarely manifest as a neonatal disease within a family characterized by otherwise typical ADPKD. Coinheritance of a hypomorphic PKD1 allele in trans with an inactivating PKD1 allele is one mechanism that can cause early onset(More)
Mutations in the methyl-CpG-binding protein-2 (MECP2) gene on Xq28 have been found to be a cause of Rett syndrome (RS). In a previous mutation screening, we found MECP2 mutations in 81% of Swedish classical Rett women. In this study, we have analyzed 22 patients for MECP2 deletions using multiplex-ligation-dependent probe amplification (MLPA). Clinically,(More)
Larsen syndrome (LS) is a skeletal dysplasia (osteochondrodysplasia) in which multiple dislocations of the large joints are the major feature. Nosology in this group of diseases, which constitutes 8% of Mendelian disorders in man, is primarily based on clinical and radiographic features. Hopes for more accurate classification grounds are currently being met(More)
A girl fulfilling four/five of six inclusion criteria and eight/nine of 11 supportive criteria for atypical Rett syndrome had a cytogenetic deletion of chromosome 3p, del(3)(pter-->3p25.1 approximately 25.2). The deletion was situated on the maternally derived chromosome and by molecular analysis the deletion breakpoint was shown to be between DNA markers(More)
Hereditary multiple exostoses (HME) is a well known autosomal dominant hereditary orthopedic disorder. Isolated exostoses, on the other hand, occur as sporadic events or as secondary post-traumatic sequel. The occurrence of solitary exostoses in individuals from pedigrees affected with HME may distort conclusions about carrier status and/or diagnosis. Both(More)
Autosomal dominant Holt-Oram syndrome (HOS) is caused by mutations in the TBX5 gene and is characterized by congenital heart and preaxial radial ray upper limb defects. Most of the TBX5 mutations found in patients with HOS cause premature truncation of the primary TBX5 transcript. TBX5 missense mutations alter the three-dimensional structure of the protein(More)
Six male patients with infantile autism and an extra inverted duplicated chromosome 15[inv dup(15)] were reported in a previous study. These patients had four copies of the chromosome region 15pter-q13, or an inv dup(15)(pter>ql3; >q13->pter). In this new study, DNA from the families of four of the patients were analysed using Southern based RFLPs and(More)
Autism spectrum disorder, severe behaviour problems and duplication of the Xq12 to Xq13 region have recently been described in three male relatives. To describe the psychiatric comorbidity and dysmorphic features, including craniosynostosis, of two male siblings with autism and duplication of the Xq13 to Xq21 region, and attempt to narrow down the number of(More)
We have assigned the human tripeptidyl peptidase II (TPP2) gene to chromosome region 13q32-q33 using two different methods. First, a full-length TPP2 cDNA was used as a probe on Southern blots of DNA from a panel of human/rodent somatic cell hybrids. The TPP2 sequences were found to segregate with the human chromosome 13. Second, fluorescence in situ(More)
