Long-term follow-up of three individuals with Kabuki syndrome indicates their phenotype becomes less striking as adults. It is characterized by short stature, obesity, and relatively large head. Long palpebral fissures persist, as does mild to moderate mental retardation. Independent daily living skills are achieved but a sheltered living environment is needed.

Monosomy 1p36 may result in a clinically recognizable chromosomal microdeletion syndrome. We report the unexpected death of a 12 year old boy with mildly dysmorphic facial features, short stature at 138 cm (3rd centile), moderate mental retardation and a history of seizures, obesity, transient muscle weakness of the right arm and leg and episodes of transient atonic hemiparesis of the right side of the body. Despite the relatively few congenital anomalies and normal karyotype, the 1p36 deletion was suspected on clinical grounds and was demonstrated by fluorescent in situ hybridisation (FISH). Two months after diagnosis and following a short history of a mild upper airway infection, high fever and severe diarrhea, the patient had a massive circulatory shock and asystolia, resulting in deep coma, brain edema, apallic syndrome and death. To our knowledge there has been no previous report of episodes of transient unilateral muscle weakness and atonic hemiparesis, circulatory shock and sudden death associated with monosomy 1p36.

Prader-Willi syndrome is a multisystem neurogenetic obesity disorder with behavioral manifestations, including hyperphagia, compulsive behavior, self-injury, and mild to moderate mental retardation. In an 8-week open-label study, we evaluated adjunctive therapy with the anticonvulsant topiramate in 8 adults with Prader-Willi syndrome. Appetite was measured by a 1-hour access to food four times throughout the study and quantified with a visual analogue scale. Topiramate did not significantly change calories consumed, Body Mass Index, or increase self-reported appetite. In addition, there were no significant changes in compulsions. Surprisingly, topiramate treatment resulted in a clinically significant improvement in the self-injury (i.e., skin-picking) that is characteristic of this syndrome. Potential benefits of topiramate for self-injury should be evaluated further in controlled trials.

We describe the case of a boy with moderate mental retardation associated with tall stature, obesity, macrocephaly and typical facial features, characterized by a large 'square' forehead, prominent supraorbital ridges, broad nasal tip, prominent lower lip and minor dental anomalies. We think that our proband is affected by Clark-Baraitser syndrome, a rare X-linked mental retardation disorder, to date described only in five male subjects. We present a more complete definition of the clinical phenotype of the syndrome with particular attention to the behavioural aspect that, in combination with the body size and the dysmorphic picture, we think is distinctive for the Clark-Baraitser syndrome. We also summarize the mild features described in female relatives of the patients, as it could disclose a possible carrier condition and be of help with genetic counselling in the families with male patients, until a molecular test is available.

A consanguineous pedigree is described where 14 individuals are affected with a novel autosomal recessive disorder, which causes static moderate mental retardation, truncal obesity, a congenital nonprogressive retinal dystrophy and micropenis in males. We have tentatively named this condition MORM syndrome. It shows similarities to Bardet-Biedl syndrome and Cohen syndrome, but can be distinguished by clinical features; the age of onset and nonprogressive nature of the visual impairment, the lack of characteristic facies, skin or gingival infection, microcephaly, 'mottled retina', polydactyly and small penis without testicular anomalies. Furthermore, linkage to the known Bardet-Biedl (BBS1-8) and Cohen syndrome loci was excluded. Autozygosity mapping identified a single homozygous subtelomeric region shared by all affecteds on chromosome 9q34.3, with a maximum LOD score of 5.64. We believe this to be the first example of the identification of a subtelomeric recessive locus by autozygosity mapping.

Anterior cervical hypertrichosis or hairy throat is a rare dysmorphic sign described in a total of 19 patients so far. The association with a number of additional features has been reported, including mental retardation. We report on another patient with this condition who also had moderate mental retardation, mildly dysmorphic facial features, obesity, hypermetropia and additional hair anomalies (low dorsal hair line on the neck, lumbosacral hypertrichosis). Karyotype and array comparative genomic hybridization analysis at 1 Mb resolution were normal.

The association of obesity, phenotypic abnormalities and mental retardation characterizes syndromic obesity. Its most common form is the Prader-Willi syndrome (PWS-- neonatal hypotonia, poor sucking, delayed psychomotor development, hyperphagia, severe obesity, short stature, small hands and feet, hypogonadism, mild to moderate mental retardation and behavioral disorders). A PWS-like phenotype has been described in patients with chromosome abnormalities involving the chromosome region 6q16.2 that includes the SIM1 gene. Herein we report cytogenetic and gene studies including a screening for the SIM1 gene deletion, performed on 87 patients with PWS-like phenotype, and describe the fifth case of syndromic obesity with an interstitial deletion of the chromosome segment 6q16-q21 and suggest that mutational analysis and further studies of the parental origin of chromosome alterations of 6q16.2 in patients with and without PWS-like phenotype are needed to evaluate possible imprinting effects of SIM1 gene and establish the contribution that alterations in this gene makes to the etiology of syndromic and non-syndromic obesity.

Bardet-Biedl syndrome (BBS) is a ciliopathy causing multivisceral abnormalities. Its prevalence in Europe is from 1/125,000 to 1/175,000. This disorder is defined by a combination of clinical signs: obesity, pigmentary retinopathy, post-axial polydactyly, polycystic kidneys, hypogenitalism, and learning disabilities, many of which appearing after several years of evolution. Individual clinical phenotype is highly variable. Most signs are present in a majority of patients but only pigmentary retinopathy is constant after infancy. There are many other associated minor clinical signs including diabetes, blood hypertension, congenital cardiopathy or Hirschsprung disease. This broad clinical spectrum is associated to a great genetic heterogeneity, with mainly an autosomal recessive transmission and, sometimes cases of oligogenism. To date, mutations in 12 different genes (BBS1 to BBS12) are responsible for this phenotype. These genes code for proteins involved in the development and function of primary cilia. Absent or non functional BBS proteins affect cilia in certain organs such as kidney or eye. However, some symptoms are still not clearly related to cilia dysfunction. BB syndrome has to be recognized because a molecular diagnosis is possible and will lead to familial genetic counseling and possibly prenatal diagnosis. Patients with BBS will need a multidisciplinary medical care. The renal abnormalities are the main life-threatening features because they can lead to end-stage renal failure and renal transplantation. Retinal dystrophy leading to progressive vision loss, moderate mental retardation, and obesity will affect social life of these patients.

Albright hereditary osteodystrophy (AHO), also known as Martin-Albright syndrome (MAS), is a rare autosomal dominantly transmitted disease characterized by short stature, obesity, mental retardation, a round facies, and brachymetacarpia and -tarsia, as well as cutaneous calcification. The disease is caused by mutations in the GNAS gene localized on chromosome 20q13.2 encoding for an adenyl-cyclase-stimulating protein (Gsalpha). A 58-year-old patient presented with small stature since childhood, moderate mental retardation, round facies and soft tissue masses on the thighs. A biopsy of the latter showed subcutaneous ossification. Laboratory results showed hypocalcemia, as well as increased plasma levels of PTH and calcitonin. The clinical diagnosis was confirmed by detection of reduced activity of Gsalpha. In patients with cutaneous calcification and disturbed calcium metabolism, AHO is an important differential diagnostic consideration.

A 4-year old boy was referred for evaluation of renal failure, posterior urethral valve (PUV) and urinary tract infection. His parents added complaints of polyuria, polydipsia, enuresis, shortness of stature, and inappropriate obesity. Serum blood urea nitrogen and creatinine levels were 45 and 3.5 mg/dL, respectively. Urine culture was positive for Pseudomonas aeruginosa, and abdominal ultrasound revealed bilateral small kidneys. The patient's history included mild to moderate mental retardation and postaxial polydactyly of both lower limbs amputated two years ago. The combination of mental retardation, obesity, postaxial polydactyly, and bilateral renal hypoplasia were compatible with the diagnosis Bardet-Biedl syndrome (BBS). The combination of PUV and BBS is a rare condition that caused this early onset of renal failure and inappropriate obesity guided us to the diagnosis.
