Epidermolysis bullosa simplex with mottled pigmentation: clinical aspects and confirmation of the P24L mutation in the KRT5 gene in further patients.

Epidermolysis bullosa simplex with mottled pigmentation (EBS-MP) is a rare dermatologic disorder of autosomal dominant inheritance with intraepidermal blistering after minor trauma, reticular hyperpigmentation unrelated to the blistering, nail dystrophy, and mild palmoplantar keratosis. Keratin 5 and keratin 14 are known to be essential for the basal keratinocyte cytoskeleton and are defective in several forms of epidermolysis bullosa simplex. Recently, a 71C-->T transition in the keratin 5 gene (KRT5) causing a P24L substitution was identified in some patients with EBS-MP. We present a family with three affected members and a sporadic patient with EBS-MP. They exemplify clinically mild expression with intrafamilial variability and the possibility of improvement with time. In all of them, mutation analysis of the KRT5 gene showed the P24L mutation. So far, other mutations in the same or in other genes have not been reported in patients with EBS-MP.

Two sibs with an unusual pattern of skeletal malformations resembling osteogenesis imperfecta: a new type of skeletal dysplasia?

We report a 6 year old boy with multiple fractures owing to bilateral, peculiar, wave-like defects of the tibial corticalis with alternative hyperostosis and thinning. Furthermore, he had Wormian bones of the skull, dentinogenesis imperfecta, and a distinct facial phenotype with hypertelorism and periorbital fullness. Collagen studies showed normal results. His sister, aged 2 years, showed the same facial phenotype and dental abnormalities as well as Wormian bones, but no radiographical abnormalities of the tubular bones so far. The mother also had dentine abnormalities but no skeletal abnormalities on x ray. This entity is probably the same as that described in a sporadic case by Suarez and Stickler in 1974. In spite of the considerable overlap with osteogenesis imperfecta (bone fragility, Wormian bones, and dentinogenesis imperfecta), we believe this disorder to be a different entity, in particular because of the unique cortical defects, missing osteopenia, and normal results of collagen studies.

Sibs with Axenfeld-Rieger anomaly, hydrocephalus, and leptomeningeal calcifications: a new autosomal recessive syndrome?

The Axenfeld-Rieger anomaly is a defect of the anterior chamber of the eye affecting the angle structures. If accompanied by hypodontia, midface hypoplasia, and umbilical anomalies, the designation "Rieger syndrome" is appropriate. Both conditions are autosomal dominant traits. The Axenfeld-Rieger anomaly is also known to occur in a variety of other syndromes. We report on two sisters, born to consanguineous parents, who presented with Axenfeld-Rieger anomaly, hydrocephalus, leptomeningeal calcifications, and mild mental retardation. Their height was on and just below the 3rd centile, respectively. One of them suffered from epilepsy and the other from sensorineural hearing loss. Two of their brothers died at young ages of hydrocephalus and possibly had intracranial calcifications as well. The differential diagnosis is discussed. Of the known syndromes associated with Axenfeld-Rieger anomaly, none could be convincingly applied to the propositae. Possibly, they represent a previously unreported autosomal recessive syndrome.

Spasticity, mental retardation, macrocephaly and distinct craniofacial appearance: confirmation of a new subtype of complicated spastic paraplegia?

Spasticity, mental retardation, macrocephaly and distinct craniofacial appearance: confirmation of a new subtype of complicated spastic paraplegia?: In this report, we describe a 30-year-old female with mental retardation, spastic paresis, epilepsy, macrocephaly and distinct craniofacial appearance. Probably, she suffers from the same condition as the two sibs described by Fryns et al., in 1994 (2).

Oculocerebrocutaneous syndrome: report of three additional cases and aetiological considerations.

The oculocerebrocutaneous (OCC) syndrome is characterized by the presence of orbital cysts and microphthalmia/anophthalmia, focal hypo- and aplastic skin defects, skin appendages and cerebral malformations. Most of the patients suffer from psychomotor retardation and seizures. To date, 23 patients in total have been reported. We report on three additional cases which illustrate the broad clinical spectrum of this disorder. In one case, the differentiation between OCC syndrome and encephalocraniocutaneous lipomatosis was difficult. A brief review of the clinical features of OCC syndrome is given. Possible aetiological hypotheses are discussed, namely survival of a lethal mutation by mosaicism, an autosomal dominant mutation and external causal factors. Disruption of the anterior neuroectodermal plate seems to be the most probable pathogenic mechanism.

Marker chromosome identification by micro-FISH.

Micro-FISH was used to elucidate the chromosomal origin of marker chromosomes in three patients. Ten copies of marker chromosomes were collected with microneedles from GTG banded metaphases, transferred to a collecting drop and amplified by means of DOP-PCR. The PCR products were labeled with biotin-14-dATP and used as FISH probes for hybridization to normal metaphase chromosomes and to metaphase chromosomes of the patients (reverse painting). With the generation of chromosome region-specific painting probes by PCR amplification of microdissected DNA and subsequent FISH it was possible to identify the marker chromosomes in all patients. One marker appeared to be derived from the centromere region of the X-chromosome and the proximal third of the long arm, one from the centromere region of chromosome 17 and one marker chromosome was identified as an isochromosome 18p.

Alagille syndrome in a family with duplication 20p11.

Alagille syndrome (arteriohepatic dysplasia, AHD) is a well defined genetic disorder with five major features: distinctive facies, cardiovascular anomalies, paucity of interlobular bile ducts (PILBD), ocular anomalies and minor skeletal malformations. Repeatedly, structural anomalies of 20p, in most cases a deletion, have been described in patients with Alagille syndrome. We report a three generation family with AHD presenting with typical facial dysmorphology, cardiac and ocular lesions but without clinical signs of liver manifestation. Two infants died from a complex cardiovascular malformation consisting of pulmonary valve atresia, hypoplasia of the pulmonary arteries and VSD. The diagnosis was not appreciated until ocular anomalies were found in the father and the distinctive facies became apparent in the daughter. Chromosome region 20p could not be interpreted precisely by high resolution banding. Using in situ hybridization a duplication 20p11.21-p11.23 was found segregating with the disorder in the family.

Oculocerebrocutaneous syndrome: a case report, a follow-up, and differential diagnostic considerations.

Oculocerebrocutaneous syndrome consists essentially of orbital cysts and microphthalmia/anophthalmia, focal dermal defects, skin appendages and malformations of the central nervous system. Up to now, about 20 sporadic cases have been reported. Limited information is available on the clinical spectrum and on the natural history. We present the long-term follow-up of a 19 year-old patient who was one of the first two patients described by Delleman and Oorthuys in 1981. Furthermore, we report on a new case presenting with bilateral anophthalmia and orbital cysts, typical skin lesions, a complex brain malformation and cleft lip palate. This infant died due to the severe cerebral malformations at the age of 10 months. Encephalocraniocutaneous lipomatosis, focal dermal hypoplasia and microphthalmia with linear skin defects (MLS) syndrome are discussed as the most important differential diagnostic entities.

ICF syndrome: a new case and review of the literature.

Patients with ICF syndrome can be recognized by the presence of a variable immunodeficiency, instability of the pericentromeric heterochromatin of, in particular, chromosomes 1, 9, and 16 in cultured peripheral lymphocytes, and a number of facial anomalies. Recently, aberrations at the molecular level have been described, consisting of alterations in the methylation pattern of classical satellite DNA, in a number of patients. ICF syndrome is considered to be inherited in an autosomal recessive manner and may be rare, as only 14 patients have been described thus far. We present a new case, a boy with agammaglobulinemia, who was extensively studied by means of classical cytogenetics and fluorescent in situ hybridization. All patients previously reported in the literature are reviewed.

Partial trisomy of the short arm of chromosome 18 due to inversion duplication and direct duplication.

We report one patient with a de novo inversion duplication 18 (pter-->cen) and two cases of direct tandem duplication 18 (pter-->cen), one due to maternal inheritance and the other arising as mosaicism of unknown origin. The duplications are demonstrated by high resolution banding. They were verified by in situ hybridization with a paint specific for chromosome 18 and with DNA probe LI.84 specific for the centromere region of chromosome 18. FISH with the genomic DNA probe pHRR68 specific for 18p11.32 revealed a subtle deletion concomitantly involved in the case of inversion duplication 18p. The patients exhibit slight developmental delay/moderate mental retardation and only a few dysmorphic features. The literature on trisomy 18p is reviewed and the present cases are compared to it.
