Autosomal recessive cleft lip/palate, ectodermal dysplasia, and minor acral anomalies: report of a Brazilian family.

We report on a Brazilian woman, born to consanguineous (first cousin) parents (F = 1/16) and presenting cleft lip/palate, ectodermal dysplasia, interdigital webbing, and other malformations. Parental consanguinity and possible recurrence in sibs suggest autosomal recessive inheritance. The nosologic aspects with the Martinez syndrome and with the Zlotogora-Ogur syndrome are discussed.

Hair-nail dysplasia--a new pure autosomal dominant ectodermal dysplasia.

An apparently hitherto undescribed pure ectodermal dysplasia of the tricho-onychic subgroup is described. Its cause is an autosomal dominant gene with complete penetrance and variable expressivity. Differential diagnosis considered 18 conditions belonging to the same subgroup, as well as Clouston syndrome. This report increases the number of conditions of the tricho-onychic subgroup to 19, and the total number of ectodermal dysplasias to 155.

New cases of dermoodontodysplasia?

We report on 2 sisters and one brother with severe dental anomalies, trichodysplasia, onychodysplasia, and slight skin alterations. Four other relatives have only mild dental anomalies. Differential diagnosis includes 3 other ectodermal dysplasias: hypodontia and nail dysgenesis, dermoodontodysplasia, and trichodermodysplasia with dental alterations. Cause is unknown.

Two other cases of ANOTHER syndrome? Family report and update.

We describe one daughter of a possibly distant consanguineous couple with infantile hypothyroidism, trichodysplasia, dental anomalies, dystrophic nails, skin alterations, otitis media, slight conductive hypoacusia, recurrent respiratory tract infections, and gastroenterologic problems. One of her two sisters presents dental anomalies and trichodysplasia, and had dry skin at birth. Similarity indexes are estimated for our patients in comparison with those described under the acronym ANOTHER syndrome. It is concluded that, in spite of the differences, it is possible that our two patients also present ANOTHER syndrome. The cause is unknown.

Lid agenesis-macrostomia-psychomotor retardation-forehead hypertrichosis--a new syndrome?

We describe a boy with bilateral lid agenesis and total keratinization of cornea and conjunctiva, macrostomia, psychomotor retardation, forehead hypertrichosis, ocular hypertelorism, thin lips, abnormal auricles and nose, skin alterations, and other findings. Differential diagnosis with ablepharon-macrostomia syndrome is presented. Cause is unknown.

Oculotrichodysplasia (OTD): a new probably autosomal recessive condition.

A brother and sister, the offspring of first cousins, are described with retinitis pigmentosa, trichodysplasia (hypotrichosis and structural changes), dental anomalies, and onychodysplasia. This is a pure ectodermal dysplasia of the tricho-odonto-onychial subgroup, probably due to an autosomal recessive gene.

Autosomal dominant painful plantar callosities.

We describe large kindred with an autosomal dominant condition characterized by painful callosities that develop over the pressure points of the soles. These callosities are not congenital; they arise with upright ambulation.

Cleft lip/palate-oligodontia-syndactyly-hair alterations, a new syndrome: review of the conditions combining ectodermal dysplasia and cleft lip/palate.

We report on a noninbred girl with cleft lip and palate, complete absence of deciduous teeth, hypodontia of permanent teeth, hair alterations, hypertelorism, midface hypoplasia, abnormal EEG, syndactyly, and other findings. Her mother had minor anomalies which could represent the mild expression of a gene. A review on the conditions combining ectodermal dysplasia and cleft lip/palate is presented.

Christ-Siemens-Touraine syndrome--a clinical and genetic analysis of a large Brazilian kindred: I. Affected females.

A total of 27 women of a Brazilian kindred are described as having one or more signs of the Christ-Siemens-Touraine syndrome. The history and physical examination were supplemented by four sweat tests and dermatolglyphic analysis. It is suggested that this syndrome has two forms -- a major form (in males) and a minor one (in females). Two signs verified in some of our patients (mosaic patchy distribution of body hair and radial deviation of distal phalanges of index fingers) seem to be here described for the first time. A review of the literature shows a corrected sex ratio between 1 M: 1.21 F and 1 M: 2.38 F among affecteds. Since the manifestation rate of the gene among carriers was estimated at about 0.70, the actual sex ratio is expected to be not lower than 1 M: 1.40 F. Contrary to a general opinion, affected females outnumber affected males.

Christ-Siemens-Touraine syndrome--a clinical and genetic analysis of a large Brazilian kindred: II. Affected males.

We describe 13 males with Christ-Siemens-Touraine syndrome from one family. History and examination were supplemented by three sweat tests and dermatolglyphic analysis. Some of the patients had two uncommon findings (onychodystrophy and excessive lacrimation), and five had an "incomplete" form of the syndrome. Four signs (distal phalanges of fingers and toes radially and tibially deviated, respectively; facial hypochromic spots; large occipitofrontal circumference) seem to be described for the first time. The segregation proportion in the sibships with at least an affected male was found to be normal (1:1) in 44 series of data (43 from the literature), where a high ascertainment bias was present (155 affected and 68 normal males).
