120 cases of the
Williams-Beuren syndrome
were collected by 11 cardiological centres in France, to determine the incidence of the various clinical signs and to obtain information on its aetiology, outcome and treatment. The selection criteria for inclusion in the series was typical facies. No particular complications were reported during pregnancy. Boys were a little more affected than girls. The birth weight was low and problems, especially digestive, often occurred in the first months. Cardiac signs were usually detected from the first year, although the exact diagnosis was usually made later on. 3/4 patients had subaortic stenosis, which was severe in 1/3 cases. Involvement of the branches of the aorta was not looked for systematically: the incidence (1/5 cases) found was lower than the true figure. Half the patients also had stenoses on branches of the pulmonary artery, but only rarely were they severe. These vascular malformations often seem to be progressive and, over a 10 year period, half the patients deteriorated. Many extracardiac abnormalities were reported. The most frequently encountered were inguinal and/or umbilical
hernia
. Surgery on the subvalvular stenosis gave good results in over 80 p. 100 cases; operative mortality was about 10 p. 100. Surgery should be performed before irreversible coronary or myocardial lesions develop. The study of the previous history did not give any new information on the cause of the syndrome, whose association with idiopathic hypercalcaemia of infancy is emphasised once again.

The authors report a female presenting with congenital heart defects, liver hemangiomas, and facial dysmorphisms admitted to hospital at 3 months of age because of feeding difficulties and poor growth. She had hypotonia and large tongue, "coarse" face, and umbilical
hernia
in presence of complex congenital cardiovascular malformations. In spite of normal neonatal screening we performed serum levels of thyroid hormones. Thyrotropin level was very high (>50 microU/ml; normal value 0.2-4 microU/ml), while serum free T(3) (FT3) and free T(4) (FT4) levels were normal (FT3 3.6 pg/ml, normal value 2.8-5.6 pg/ml; FT4 11.6 pg/ml, normal value 6.6-14 pg/ml); antithyroid autoantibodies were absent. Thyroid scintigraphy with sodium 99m Tc pertechnetate showed a small ectopic thyroid located in sublingual position, so treatment with L-thyroxine 37.5 microg/24 hr was started with rapid improvement of the clinical picture. At 17 months of age the patient developed the complete characteristic phenotype of
Williams syndrome
(WS); the clinical diagnosis was proven by fluorescent in situ hybridization (FISH) analysis which showed hemizygous deletion of the elastin gene on chromosome 7. Recently a case of thyroid hemiagenesis in a child with WS has been reported; our patient underscores the association of hypothyroidism and WS. Moreover, our case shows that clinical manifestations of hypothyroidism may be present and the treatment may be necessary as it is in isolated congenital hypothyroidism.

Interstitial deletions of 7q11.23 cause
Williams-Beuren syndrome
, one of the best characterized microdeletion syndromes. The clinical phenotype associated with the reciprocal duplication however is not well defined, though speech delay is often mentioned. We present 14 new 7q11.23 patients with the reciprocal duplication of the
Williams-Beuren syndrome
critical region, nine familial and five de novo. These were identified by either array-based MLPA or by array-CGH/oligonucleotide analysis in a series of patients with idiopathic mental retardation with an estimated population frequency of 1:13,000-1:20,000. Variable speech delay is a constant finding in our patient group, confirming previous reports. Cognitive abilities range from normal to moderate mental retardation. The association with autism is present in five patients and in one father who also carries the duplication. There is an increased incidence of hypotonia and congenital anomalies: heart defects (PDA), diaphragmatic
hernia
, cryptorchidism and non-specific brain abnormalities on MRI. Specific dysmorphic features were noted in our patients, including a short philtrum, thin lips and straight eyebrows. Our patient collection demonstrates that the 7q11.23 microduplication not only causes language delay, but is also associated with congenital anomalies and a recognizable face.

Objective:
To explore the clinical phenotypes and the genetic cause for a boy with unexplained growth retardation, nephrocalcinosis, auditory anomalies and multi-organ/system developmental disorders.
Method:
Routine G-banding and chromosome microarray analysis were applied to a child with unexplained growth retardation, nephrocalcinosis, auditory anomalies and multi-organ/system developmental disorders treated in the Department of Pediatrics of Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology in September 2015 and his parents to conduct the chromosomal karyotype analysis and the whole genome scanning. Deleted genes were searched in the Decipher and NCBI databases, and their relationships with the clinical phenotypes were analyzed.
Result:
A six-month-old boy was refered to us because of unexplained growth retardation and feeding intolerance.The affected child presented with abnormal manifestation such as special face, umbilical
hernia
, growth retardation, hypothyroidism, congenital heart disease, right ear sensorineural deafness, hypercalcemia and nephrocalcinosis. The child's karyotype was 46, XY, 16qh
+
, and his parents' karyotypes were normal. Chromosome microarray analysis revealed a 1 436 kb deletion on the 7q11.23(72701098_74136633) region of the child. This region included 23 protein-coding genes, which were reported to be corresponding to
Williams-Beuren syndrome
and its certain clinical phenotypes. His parents' results of chromosome microarray analysis were normal.
Conclusion:
A boy with characteristic manifestation of
Williams-Beuren syndrome
and rare nephrocalcinosis was diagnosed using chromosome microarray analysis. The deletion on the 7q11.23 might be related to the clinical phenotypes of
Williams-Beuren syndrome
, yet further studies are needed.
