A patient with hypotelorism, nasomaxillary hypoplasia and cleft lip and palate is presented. The absence of an associated intracranial abnormality, mental retardation or seizures places this patient in a separate category from those described by deMyer. Her intelligence is above normal but at four years of age, she is having psychological problems and difficulties interacting with her peers.

Incontinentia pigmenti is a component of the Bloch-Sulzberger syndrome, which consists also of several major anomalies involving the central nervous system, skeleton, teeth, and the eye. Important manifestations include seizures, mental retardation, microcephaly, deformities of the skull and vertebrae, cleft palate, dystrophy of the nails, and abnormal or missing teeth. Although usually listed as a disease with which congenital cataract is associated, the more important ocular findings are those of the posterior segment, resembling lesions that enter into the differential diagnosis of the white pupil. The skin disturbance is characteristic and occurs very early in life; it may disappear entirely, obscuring the diagnosis if the ocular lesions are discovered later. The Bloch-Sulzberger syndrome usually is inherited as an X-linked dominant with lethality for males. It is a rare but important entity to the pediatric ophthalmologist.

We describe a large, three generation kindred in which 16 individuals were affected with alopecia, hyposmia or anosmia, conductive deafness associated with protruding ears, microtia, and/or atresia of the external auditory canal, hypogonadotropic hypogonadism due to LH/FSH deficiency, and a greater than normal tendency to dental caries. Variable manifestations include mild facial asymmetry, mental retardation, congenital heart defect, and cleft palate. This seems to be a previously undescribed pleiotropic autosomal dominant trait with variable expressivity. The manifestations can be explained on the basis of involvement of the ectoderm and neuroectoderm of the first and second branchial arches, of Rathke's pouch, and of the diencephalon.

An increase of LDH A activity is observed in an adolescent patient trisomic for 11p with the exception of band 11p13. The clinical syndrome is delineated: broad faces, abundant eyebrows in their internal portion, enophtalmia, hypoplasic nasal bridge, hypertelorism, epicanthus, cleft palate or lip, macroglossia, hypotrophic muscles, soft and abundant skin, mental retardation.

A grandfather with balanced translocation t(1:10) gave rise to three possible combinations involving chromosome 10: balanced translocation and trisomy for part of the short arm 10p13 leads to pter in the second generation, and mono- and trisomy 10p13 leads to pter in the third generation. The clinical signs and symptoms of the present case with monosomy 10p13 leads to pter are compared with those of 9 earlier reported cases with a deleted 10p. Together they represent a clinically recognizable syndrome with antimongoloid eye slant, ptosis, epicanthus, high arched or cleft palate, flat nasal bridge, micrognathia, small round and low-set ears, wide spaced nipples, cardiac and urinary tract abnormalities, hand and foot anomalies, hypoplasia/absence of the olfactory bulbs/tracts, psychomotor and growth retardation. More than 20 cases of the trisomy 10p syndrome have been described earlier. The most constant clinical findings are mental retardation, dolichocephaly, frontal bossing, broad nasal bridge, cheilo-palatoschisis, retrognathia and variable internal malformations. We found, however, the clinical characteristics in this syndrome more variable than for the monosomy 10p13 leads to pter syndrome. Our two cases, representing the eldest and the youngest described, have rather few of the typical characteristics, and few in common with each other. This indicates the difficulty in making this diagnosis on clinical features only without a cytogenetic verification.

Thirty-nine patients with the velo-cardio-facial syndrome are described in order to further delineate this probably common recurrent pattern congenital malformation syndrome. Frequent features include cleft palate, cardiac anomalies, typical facies, and learning disabilities. Less frequent findings include microcephaly, mental retardation, small stature, slender hands and digits, minor auricular anomalies and inguinal hernia. Ths Robin malformation sequence was found in four patients. The congenital heart anomalies most frequently involved a ventricular septal defect, with or without a right-sided aortic arch. There were four instances of familial transmission in the sample population. These included two cases of maternal transmission of the syndrome to daughters, one case of maternal transmission to a son, and one case of maternal transmission to both a son and daughter. There was no particular difference in expression between male and female patients so that even though X-linked dominant transmission is possible, the velo-cardio-facial syndrome is likely to be an autosomal dominant recurrent pattern syndrome.

Five unrelated patients with a previously unrecognized mental retardation malformation syndrome are presented. Clinical features common to them include moderate mental retardation, postnatal dwarfism, susceptibility to infection in infancy, and peculiar craniofacial dysmorphia characterized by long palpebral fissures, high-arched and abnormal eyebrows, heavy and long eyelashes, large ears, short nasal septum and/or depressed nasal tip, and cleft palate. Other anomalies are stubby fingers, deformed vertebra and other bone and joint anomalies, and abnormal dermatoglyphics. The absence of familial occurrence and of consanguinity suggests some environmental causation, but the possibility of an autosomal dominant or X-linked mode of inheritance remains. Based upon our five patients and other five of Niikawa et al, we propose this syndrome as a new disease entity.

A 5-year-old Korean boy with diagnosis of cutis marmorata telangiectatica congenita had a bluish-red, widespread livedo network over the entire body surface. There was skin atrophy as well as ulceration and crust over some of the lesions. These abnormalities have been associated with mental retardation with abnormal EEG findings, speech disability, defective growth, cleft palate, presence of simian lines and an increase in the atd angles of both palms, diffuse demineralization of bony structure and weakness of the long extensor muscles of both thumbs. Based on our clinical datas and review of world literature, it would seem to be necessary to change the terminology.

We describe a case of tertiary trisomy (22q11q) 47,XX,+der(22),(22pter = to 22q13 :: 11q25 = to 11qter) in a child with mental retardation, cleft palate, and congenital heart disease resulting from 3 : 1 meiotic nondisjunction in a maternal (11;22) translocation carrier. The clinical findings in previously reported cases are reviewed and compared with the features of reported patients with "partial trisomy 11q" and "trisomy 22" syndromes. Half of the ten reported families had additional balanced translocation carriers who may have an increased risk of having a liveborn child with an MCA/MR syndrome, although none have been reported to date.

The Kabuki (Niikawa-Kuroki) syndrome was reported in 1981 by Niikawa et al. and Kuroki et al. in a total of ten unrelated Japanese children with a characteristic array of multiple congenital anomalies and mental retardation. The syndrome is characterized by a distinct face, mild to moderate mental retardation, postnatal growth retardation, dermatoglyphic and skeletal abnormalities. In Japan, the syndrome appears to have an incidence of about 1:32,000 newborns. Outside of Japan, a growing number of patients have been recognized. Clinical data are presented on 29 Caucasian patients; the patients were diagnosed over a relatively short period of time, indicating that the incidence outside of Japan is probably not lower than in Japan. A literature review of 89 patients (60 Japanese and 29 non-Japanese) is given. In 66% of the non-Japanese patients serious neurological problems were present, most notably hypotonia and feeding problems (which were not only related to the cleft palate); this was not reported in the Japanese patients. Inheritance is not clear. Most patients are isolated, sex-ratio is equal. The syndrome can be recognized in patients with cleft (lip/)palate, with mild to moderate developmental delay and in young children with hypotonia and/or feeding problems. In counselling parents, the designation "Kabuki" syndrome seems to be more appropriate than "Kabuki make-up" syndrome.
