Face morphogenesis and its troubles disturb always the patient and its family. Why? Among the ways of research about these problems the Catastrophe Theory of R. Thom is helpful. In another way the terms and words used to explain the lesions and the troubles of self-perception are examined.
We describe a newborn with multiple congenital anomalies consistent with an oro-facio-digital syndrome (OFDS). These are a group of inherited syndromes that have in common anomalies of the tongue (bifid or lobulated tongue with hamartomas), the face (median cleft lip) and the digits (brachydactyly, polydactyly, clinodactyly and/or syndactyly). OFDS has been classified into 11 types. The case described in this paper had manifestations overlapping with OFDS II (Mohr) and OFDS IV (Mohr-Majewski) and OFDS VI (Varadi). We propose that the present patient has a new variation of the OFDS due to the co-existence of the very atypical combination of polydactyly, cerebellar hypoplasia, hypothalamic hamartoma and classical facial findings of OFDS.

During routine ultrasound screening at 12 weeks 5 days of gestation, a nuchal translucency of 7 mm, an omphalocele, and fetal hydrops were found and prompted chorionic villus sampling at 13 weeks 2 days. Chromosome analysis showed an unbalanced karyotype with an abnormal chromosome 14. The mother was a carrier of a translocation karyotype 46,XX,t(13;14) (q34;q32.2). In the fetus this gave rise to a partial trisomy 13q and partial monosomy 14q (fetal karyotype: 46,XX,der[14]t[13;14][q34;q32.2]). By Array-CGH on DNA extracted from a postmortem skin culture, a duplication of approximately 1.7 Mbp of the distal part of chromosome 13q34 and a deletion of approximately 6.0 Mbp of the distal part of chromosome 14q32.2 was demonstrated. Postmortem findings after termination of pregnancy at 14 weeks 6 days included, among others, a severe hypoplasia of the median part of the maxilla, no recognizable nose, a broad median palatoschisis, nonlobulated lungs, a horseshoe kidney with multicystic dysplasia, and decreased development of cortical cellularity in the thymus. These clinical manifestations and autopsy findings of the fetus are compared with those of previously published cases and the possible involvement in this pathology of the YY1 and JAG2 transcription factors and the BCL11b and SIVA-1 regulators of thymic development is discussed.

We describe three siblings who presented with short stature, hyperactivity, delayed speech and moderate psychomotor retardation. In addition, they had dysmorphic features, a peculiar combination of skeletal abnormalities, small kidneys and exaggerated fasting ketosis. We suggest that they represent a new syndrome. The possibility of end-organ receptor failure is suggested.

A boy, born to first cousin parents of Algerian origin, first presented at the age of 9 years with growth failure, mental retardation, and dysmorphic facies. Progressive vitiligo developed from the age of 12 and distal duplication of the urethra was later recognised. The basis of this syndrome remains to be determined; autoimmune disease, chromosomal breakage syndromes, and other neurocutaneous syndromes have been excluded.

We report on the association of absent patellae, genital and renal anomalies, dysmorphic features, and mental retardation in seven children (six boys and one girl) belonging to five unrelated families. Flexion deformities of the knees and hips with club feet and absent patellae were consistently observed and scrotal hypoplasia and cryptorchidism were present in all boys (6/6). Dysmorphic features included a coarse face, a large nose with a high nasal bridge, and microcephaly. Other features included renal anomalies (multicystic kidneys or hydronephrosis, 7/7), agenesis of the corpus callosum (4/7), swallowing difficulties, micrognathia (4/7), and pulmonary hypoplasia (3/7). Bilateral hypoplasia of the ischia and brachydactyly were also consistently observed (5/5). In two out of seven cases, prenatal ultrasound detection of microcephaly and renal anomalies led to termination of the pregnancy at 27 weeks. Three children died during the first years of life and the remaining two who survived exhibit severe developmental delay. High resolution cytogenetic studies performed on lymphocytes or fibroblasts or both were normal in all cases. Recurrence in two families suggests an autosomal recessive mode of inheritance. We propose that this unusual association, similar to that observed in a 4 year old boy by Goldblatt et al, represents a new syndrome distinct from previously reported hypoplastic patella syndromes.
