Encephalocraniocutaneous lipomatosis and oculocerebrocutaneous syndrome. A differential diagnostic problem?

The authors describe a female patient with unilateral malformations of skin, cerebrum and eye. The symptoms consisted of local skin hypoplasia, skin appendages and lipomatous tissue; cysts, hypoplasia and lipomatosis of the brain; and ocular malformations. In the newborn period the symptoms led to the diagnosis of oculocerebrocutaneous (OCC) syndrome. In the first year of life the clinical course deteriorated and the psychomotor development was progressively retarded. Evaluation at the age of 15 months prompted the authors to change the diagnosis to encephalocraniocutaneous lipomatosis (ECCL). The differential diagnosis of ECCL and OCC syndromes is discussed and a possible common pathogenetic pathway of these two rare disorders is proposed.

Confirmation of X-linked inheritance and provisional mapping of the keratosis follicularis spinulosa decalvans gene on Xp in a large Dutch family.

In a large Dutch family with keratosis follicularis spinulosa decalvans (KFSD, MIM 308800), DNA linkage analysis was performed in order to locate the gene. Pedigree analysis and lod score calculation confirmed X-linked inheritance and revealed significant linkage to DNA markers on Xp. A maximum lod score of 5.70 at theta = 0.0 was obtained with DXS41 (p99.6). The KFSD gene is tentatively located on Xp21.2-p22.2.

Linkage analysis of keratosis follicularis spinulosa decalvans, and regional assignment to human chromosome Xp21.2-p22.2.

Keratosis follicularis spinulosa decalvans (KFSD) is a rare X-chromosomal disorder. It consists of follicular hyperkeratosis of the skin, scarring alopecia of the scalp, absence of the eyebrows, and corneal degeneration. There is photophobia in childhood, but the symptoms tend to diminish after puberty, and prognosis for vision is good. Some heterozygotes do show clinical symptoms. In a large Dutch pedigree we performed DNA analysis in order to localize the KFSD gene. In 54 individuals, including 21 affected males, RFLP analysis was done using DNA probes covering the X chromosome. Two-point linkage analyses with 19 informative DNA markers revealed significant linkage to DNA probes on Xp21.1-p22.3. The highest lod scores of 5.70 and 4.38 were obtained with DXS41 and DXS16 at a recombination fraction of zero and 4 cM, respectively. Multipoint linkage data place KFSD between DXS16 and DXS269. Our data confirm X linkage of KFSD in this family and tentatively map the gene on Xp22.2-p21.2. Combined with clinical investigation, RFLP analysis may become an important tool in carrier detection.

Cartilage hair hypoplasia, metaphyseal chondrodysplasia type McKusick: description of seven patients and review of the literature.

We describe 7 cases of cartilage hair hypoplasia (CHH) with emphasis on the clinical and immunological aspects. The literature on CHH is reviewed and symptoms in 63 non-Amish cases are summarized. In this autosomal recessive disorder the immunodeficiency, hair abnormalities, and severity of skeletal involvement show extremely variable expressivity, between and within families. Two of the 3 sib-pairs among our cases demonstrate the great difference in expression within one family. At adult age roentgenological abnormalities can be very mild, or even absent. An impairment in cell-mediated immunity is present in all of our cases and seems a consistent manifestation in CHH; however, sometimes it is very subtle and without clinical symptoms.

[Prognosis in the cri-du-chat syndrome].

Cri-du-chat syndrome (5p-) is one of the most frequently occurring chromosomal deletion syndromes in man. Clinical findings have been described extensively in literature, but documentation of the patients' mental development has been poor. Recently the clinical heterogeneity and variance in psychomotor development was studied in a large series of patients. Review of the literature revealed that some 15% of the cases were found to be familial, there appears to be a slight correlation between karyotype and phenotype and the positive effects of early stimulation programs on the patients' prognosis is pointed out. Some 60% of the patients need regular medical care and nearly all are mentally retarded. However a wide spectrum of developmental abilities is displayed and a number of patients can be reared at home for several years. Life expectancy depends on the number and severity of birth defects.
