normal pregnancy but born at 39,5 weeks of gestation by caesarean section because of breech delivery. Birth weight: 2590g, length: 45 cm OFC: 33cm. Development was considered as normal up to 9 months, the age at which she was referred to neurologist for a motor developmental delay. 20 months said her first words but she was not able to walk alone; height and weight were at the 50th percentile except for the head circumference that was 50,5 cm (90th percentile). Physical examination showed broad forehead, asymmetrical facial appearance, plagiocephaly and short nose with anteverted nostrils; extremities long and slender. Audiograms performed at thirty month revealed a moderate deafness.

Except for reduced fetal movements and dietetically managed gestational diabetes during the last 8 weeks, pregnancy and delivery were normal. Born in 37th week of gestation, birth weight: 3,665 g, birth length: 54 cm, head circumference: 37 cm; APGAR 9/10/10. Hypotonia, poor sucking, reduced spontaneous movements, pale skin color, reduced cardiac efficiency due to aortic insufficiency and aortic root ectasia, atrial septum defect type II and a patent Ductus arteriousus. At 13 months the atrial septum defect was treated by interventional cardiac catheterization. At the age of 12 days was noted thin long hands and fingers, thin long feet and toes, broad nasal bridge, epicanthal folds, telecanthus, retrognathia, high arched palate, and dysplastic ears with prominent helix were present. Dilatated lateral ventricles and a plexus choroideus cyst were detected by ultrasonography of the brain. At the age of 13 weeks initially long fingers and toes were normal in length and the retrognathia was less pronounced. Hypotonia had improved by physiotherapy. Developmental gross motor milestones were achieved delayed: sitting at 12 months, crawling at 13 months. Hearing impairment as a result of recurrent inflammations of the middle ear. At the age of 14 months, able to utter some different sounds and to vary the tone pitch but she did not form double syllable-chains. Fine motor and grasping movements seemed to be age-appropriate. The infant is approximately 6 months delayed in psychomotor development.

at birth: 4030g (>97th centile), length 51 cm (75th centile) and OFC 36 cm (50th centile). No clinical symptoms in neonatal period. Motor development was slightly delayed: she was hypotonic at birth and was sitting at age of 9 months; walking abilities were in the normal range and since the age of 12 months, she could walk without support. However, speech was severely delayed: first words were not until 3 years of age, and her language skills were delayed with poor performances on the expressive side. No hearing loss. At 5 y language delay, weight24.8 kg (95th centile), height 114 cm (90th centile), and OFC 53 cm (97th centile). Flat face, high and prominent forehead, deep-set eyes, short nose, prominent nasal root close to frontal bone, short philtrum, thick columella, thin lips, relative microstomia with downturned corners, and low set ears, fingers had wide nails; a partial cutaneous syndactyly was present between 2nd and 3rd toe, hirsutism on the dorsal side of her limbs and a cafe´-au-lait macula on the abdomen. Her slightly retarded psychomotor development improved with time.

Facial dysmorphic was consistent with Williams Beuren Syndrome Critical Region (WBSCR) duplicated patients. Macrocephaly was also observed (+4SD). MRI showed non-specific posterior white substance anomaly andcardiac ultrasound was normal.
