Possible relationship between ulnar-mammary syndrome and split hand with aplasia of the ulna syndrome.

We describe a 3-generation family in which mother, maternal grandfather, and 2 (male and female) children have variably manifestations of the ulnar-mammary syndrome, including ulnar ray defects, obesity, hypogenitalism, delayed puberty, hypoplasia of nipples and apocrine glands, and a previously undescribed ectopia of upper canines. The index patient also had split-hand appearance on the right due to complete absence of the 4th ray. To our knowledge this is the first documented example of split hand in the ulnar-mammary syndrome. The hand anomaly raises the question of a possible causal relationship between ulnar-mammary syndrome and the split hand with aplasia of the ulna syndrome, as already hypothesized by Lenz [1980].

Ullrich-Turner phenotype with unusual manifestation in a patient with mosaicism 45,X/47,XX,+18.

We report on a girl with Ullrich-Turner phenotype and 45,X/47,XX,+18 chromosomal mosaicism. Only two other patients with similar mosaicism have been reported, both girls with XY sex chromosome constitution. The face of the patient was highly asymmetric, the right side being almost normal, the left showing a typical Ullrich-Turner syndrome appearance. This clinical impression was strengthened by photographic doubling of both hemifaces. The patient had normal intelligence and did not show any stigmata of trisomy 18.

Lower lip pits and complete idiopathic precocious puberty in a patient with Kabuki make-up (Niikawa-Kuroki) syndrome.

We report on a 13 1/2-year-old patient with Kabuki make-up syndrome and complete idiopathic precocious puberty manifested at 7 1/2 years. In addition to the other specific clinical signs, she showed hypodontia and lower lip pits, as typically seen in the Van der Woude syndrome. The significance of lower lip pits in the Kabuki make-up syndrome is discussed.

Short rib-dysplasia group (with/without polydactyly): report of a patient suggesting the existence of a continuous spectrum.

We report on a patient with manifestations typical of Mohr syndrome and of the short rib (polydactyly) syndromes (SR(P)S) Majewski, Verma-Naumoff, Beemer, and Jeune. It seems possible that the different types of SR(P) syndromes, rather than being distinct conditions, are part of a large disease spectrum. The frequent overlap between orofaciodigital syndromes and SR(P) syndromes may be interpreted as the outcome of deletions of different size within the same chromosome region.

Inguinal hernia and atrial septal defect in Tel Hashomer camptodactyly syndrome: report of a new case expanding the phenotypic spectrum of the disease.

We report on a girl with Tel Hashomer camptodactyly syndrome (THCS) born to first-cousin parents. In addition to the usual findings, the patient had bilateral inguinal hernia and atrial septal defect, not previously described as component manifestations of the syndrome. The present description expands the phenotypic spectrum of the syndrome and gives new support to the hypothesized pleiotropic effects of the THCS gene on connective tissue.

Rigid mask-like face, ear anomalies, deafness, preaxial polydactyly and toe malformations in a patient with normal intelligence: a new entity?

We describe a patient with deafness, normal intellect and a unique phenotype characterized by a rigid mask-like face, narrow, upslanting palpebral fissures, flat malar bones, thick lower lip, malformed auricles, preaxial polydactyly with triphalangeal thumbs, syn-ectrodactyly of toes and first degree hypospadias.

Variability of clinical and immunological phenotype in immunodeficiency-centromeric instability-facial anomalies syndrome. Report of two new patients and review of the literature.

Immunodeficiency-centromeric instability-facial anomalies (ICF) syndrome is a condition characterized by variable combined immunodeficiency, developmental delay, facial anomalies and a variety of structural chromosomal rearrangements. Recently, aberrations at the molecular level have been described consisting of alterations in the methylation pattern of classical satellite DNA. To our knowledge 15 subjects have been described so far in the literature showing marked phenotypic variability. We report on two new patients with normal development and some peculiar clinical and immunological manifestations. All patients previously reported in the literature are reviewed. CONCLUSION. The identification of these two cases among our hypogammaglobulinaemic patients suggests that ICF syndrome is not a rare disorder and it should be always taken into account in immunodeficient patients with facial abnormalities.

The Williams syndrome: an Italian collaborative study.

Williams syndrome (WS) is a multiple congenital anomalies/mental retardation syndrome caused by a microdeletion on the long arm of chromoome 7 including the elastin gene. Possibly it is a contiguous gene syndrome with autosomal dominant transmission. Seventy-seven WS patients from 11 Italian Pediatric-Dysmorphology-Genetics Units were collected by means of a questionnaire designed to draw a comprehensive clinical picture, to define the frequency of different traits and associations thereof, to better understand the clinical evolution, to improve the prognosis and to ameliorate the follow-up. The most important signs for diagnosis, based on their relative frequencies, are: mental retardation with characteristic outgoing behaviour and hoarse voice; facial findings like stellate iris, periorbital fullness and thick lips; congenital heart disease. The frequency of the clinical signs reported in our patients are on the whole concordant with those found in the literature; the only significant differences concern low stature, hallus valgus, hypoplastic nails, joint contractures and ear infections. The multisystemic nature of this syndrome requires a coordinated and integrated approach in order to avoid fragmentary interventions.
