Rubinstein-Taybi syndrome (RTS) is a malformation syndrome characterised by facial abnormalities, broad thumbs, broad big toes, and mental retardation. In a subset of RTS patients, microdeletions, translocations, and inversions involving chromosome band 16p13.3 can be detected. We have previously shown that disruption of the human CREB binding protein(More)
Townes-Brocks syndrome (TBS) is an autosomal dominantly inherited malformation syndrome characterized by anal, renal, limb, and ear anomalies. Recently, we showed that mutations in the putative zinc finger transcription factor gene SALL1 cause TBS. To determine the spectrum of SALL1 mutations and to investigate the genotype-phenotype correlations in TBS, we(More)
We have performed linkage analysis with the DNA markers DXS52 and the clotting factor VIII gene (F8C), in several large families with X-linked adrenoleukodystrophy (ALD). The tight linkage to DXS52 could be extended giving a maximal LOD score of 22.5 at 1 cM. F8C was also tightly linked to ALD with a maximal LOD score of 7.8 without recombination.(More)
Two boys are described with congenital microcephaly, infantile spasms, psychomotor retardation and an early-onset nephrotic syndrome. The autopsy findings of one patient are described in detail. Polymicrogyria was the most prominent feature and the kidneys showed focal segmental glomerulosclerosis. These findings have been described as a clinical entity,(More)
We report on three Dutch children with a clinical diagnosis of oculoauriculovertebral spectrum (OAVS) and hydrocephalus. The clinical features are compared to 15 published cases of OAVS and hydrocephalus. Several other cerebral abnormalities were present in the whole group. About half of the cases had cleft lip/palate, anophthalmia/microphthalmia, or a(More)
A study based on fifteen pedigrees showed that familial glomus tumours are inherited almost exclusively via the paternal line, a finding inconsistent with autosomal dominant transmission. The results can be explained in terms of the genomic imprinting hypothesis--the maternally derived gene is inactivated during female oogenesis and can be reactivated only(More)
Osteoporosis is an important feature of osteogenesis imperfecta (OI). So far, no effective medical treatment is available. We treated three boys with severe OI type III and vertebral deformities for 5–7 years with continuous oral administration of the bisphosphonate, olpadronate. Treatment resulted in a decreased number of bone fractures, an increased(More)
Mucopolysaccharidosis type VII (MPS VII) was diagnosed in a case of severe fetal hydrops. beta-glucuronidase deficiency was demonstrated in the amniotic fluid, which was obtained at 25 weeks of gestation, and in the fibroblasts of the child, which were cultured after fetal death in the 26th week of gestation. In the amniotic fluid the two-dimensional(More)
A large family with adrenoleukodystrophy is described and the case histories of two clinically symptomatic and related male patients are presented. Clinical, biochemical and genetic screening of their family demonstrated two clinically affected males, one biochemically affected male and five carrier females. Two women were symptomatic; one suffered an acute(More)
Paragangliomas of the head and neck (glomus tumours) can occur in a hereditary pattern and may be hormonally active as well as being associated with paragangliomas elsewhere. A number of these tumours may be present without symptoms. To detect the presence of subclinical paragangliomas we screened 83 members of a family at risk of developing hereditary(More)
