Carpenter syndrome (Acrocephalopolysyndactyly type II), first described in 1901, consists of acrocephaly, syndactyly, polydactyly, congenital heart disease, mental retardation, hypogenitalism, cryptorchidism, obesity, umbilical hernia and bony abnormalities. We report a 6 years old boy presenting as a union of these malformations and also having bilateral sensorineural hearing loss. Auditory disturbances are not common among Carpenter syndrome patients. According to our knowledge, this is the first Carpenter syndrome case whose hearing loss is demonstrated by auditory brainstem response (ABR) test.

We report a case of 13-year-old girl with short stature, microcephalus, blepharophimosis, ptosis, bilateral microphthalmia (more prominent in the right), hypogonadism, other minor anomalies, and severe mental retardation. Her mother had two spontaneous abortions. She was born as the second baby of dizygotic twins. The first baby died of diaphragm hernia and heart failure. Her body height, body weight and head circumference were below -3 SD. She did not have epicanthus inversus, hypoplastic teeth, heart anomalies, seizures, muscle weakness, and hearing loss. She was able to handle her wheelchair, but could neither understand nor speak meaningful words. When she looked at something in front of herself, she turned her face up and lifted the left eyelid with her own fingers. She had no somatic change of puberty. Laboratory and radiological examinations demonstrated a normal karyotype, normal bone age, findings of Chilaiditi syndrome, and absence of brain malformation on cranial CT. The serum levels of LH and FSH were high for age and those of estradiol and progesterone were low, suggesting immaturity of ovarian function. These findings suggested the ovarian functions might not get maturations. Hypogonadism has previously been reported in female cases of the blepharophimosis, ptosis and epicanthus inversus syndrome (BPES) type I, but not in those with the Ohdo blepharophimosis syndrome (OBS). Our case's condition differs from BPES because of the presence of mental retardation and the absence of epicanthus inversus. We also discuss the distinction from OBS, a disease entity of unknown etiology presenting with a variety of complications.

We report a new patient with terminal deletion of chromosome 2 with breakpoint at 2q36 and five additional new patients with 2q terminal deletion with breakpoint at 2q37. Hemidiaphragmatic hernia is a novel finding in one patient with a breakpoint at 2q37.1. In comparing these patients to 60 previously reported individuals with 2q terminal deletions, certain physical abnormalities are loosely associated with positions of breakpoint. For example, facial features (e.g., prominent forehead, depressed nasal bridge, and dysmorphic ears and nose), short stature, and short hands and feet were frequent in patients with breakpoints at or proximal to 2q37.3. Reports of horseshoe kidney and Wilms tumor were limited to patients with a breakpoint at 2q37.1, and structural brain anomalies and tracheal anomalies were reported only in patients with breakpoints at or proximal to 2q37.1. Cleft palate was reported only in patients with the most proximal breakpoints (2q36 or 2q35). Neurological effects including developmental delay, mental retardation, autistic-like behavior, and hypotonia were typical in this patient population but did not stratify in severity according to breakpoint. Terminal deletion of the long arm of chromosome 2 should be considered in the infant with marked hypotonia, poor feeding, gastroesophageal reflux, and growth delay, and the older child with developmental delay, autistic behavior, and the characteristic facial and integumentary features described herein. Assignment of clinical features to specific breakpoints and refinement of predictive value may be useful in counseling.

Wilms tumor, aniridia, genitourinary anomalies, and mental retardation (WAGR) syndrome is a contiguous gene deletion syndrome involving the Wilms tumor 1 gene (WT1), the paired box gene 6 (PAX6), and possibly other genes on chromosome 11p13. WT1 is required for normal formation of the genitourinary system and the high incidence of Wilms tumor and genitourinary anomalies found in patients with WAGR are attributed to haploinsufficiency of this gene. It has been hypothesized that WT1 also plays an important role in the development of the diaphragm. During mammalian embryonic development, WT1 is expressed in the pleural and abdominal mesothelium that forms part of the diaphragm. Furthermore, mice that are homozygous for a deletion in the mouse homolog of WT1 have diaphragmatic hernias. Case reports describing congenital diaphragmatic hernias in infants with Denys-Drash and Frasier syndromes, both of which can be caused by mutations in WT1, provide additional support for this hypothesis. We report an infant with aniridia, bilateral cryptorchidism, vesicoureteral reflux, and a right-sided Morgagni-type diaphragmatic hernia. G-banded chromosome analysis revealed a deletion of 11p12-p15.1. Breakpoint regions were refined by fluorescence in situ hybridization (FISH) and deletion of the WAGR critical region, including WT1, was confirmed. A review of the medical literature identified a second patient with a deletion of 11p13, a left-sided Bochdalek-type diaphragmatic hernia, and anomalies that suggest a diagnosis of WAGR including bilateral microphthalmia, a small penis, bilateral cryptorchidism, and a hypoplastic scrotum. These cases demonstrate that congenital diaphragmatic hernia can be associated with WAGR syndrome and suggest that deletions of WT1 may predispose individuals to develop congenital diaphragmatic hernia.

We performed a comprehensive literature and case report review to characterize the cardiovascular malformations (CVMs) associated with Fryns syndrome (OMIM #229850), a multiple congenital anomaly/mental retardation syndrome consisting of diaphragmatic defects, significant pulmonary hypoplasia, distinctive facial appearance, distal digital hypoplasia, and numerous other external and internal anomalies. A total of 112 patients meeting diagnostic guidelines for Fryns syndrome were identified, of whom 82 met narrowly defined criteria (Group I) and 30 met broader diagnostic criteria (Group II). Twelve patients reported as having Fryns syndrome with atypical features (Group III) were also analyzed. A CVM was reported in 51% (42 of 82) of Group I patients, most commonly an atrial or ventricular septal defect (VSD) (23 of 42, 55%). Conotruncal and aortic arch CVMs were common (11 of 42, 26%), but not significantly so compared to the general population of infants to age 1 year [Ferencz et al., 1997]. Recognizing that minor septal defects associated with congenital diaphragmatic hernia (CDH) may occur in response to altered hemodynamics (instead of being a bonafide CVM), we excluded four patients reported as having hemodynamically insignificant VSDs. Following these exclusions, conotruncal CVMs were found more commonly than in the general population (11 of 38, 29%, P < or = 0.025). In Group II, 9 of 30 (30%) had a CVM with no predominant type among the small number of cases reviewed. Among the atypical Fryns syndrome patients in Group III, half (6 of 12, 50%) had a CVM; most (4 of 6, 67%) were conotruncal, in particular, type B interrupted aortic arch (3 of 4). Patients with Fryns syndrome have a high rate of CVMs, warranting thorough cardiac evaluation including echocardiogram (fetal and/or postnatal) in all patients, similar to the evaluation for other patients with diaphragmatic hernia. The possible association between conotruncal CVMs and Fryns syndrome may provide additional support for an etiologic role of genes related to neural crest cell development in the pathogenesis of Fryns syndrome and hence, congenital diaphragmatic hernia.

Hurler's disease, also known as mucopolysaccharidoses 1H, an autosomal recessive disease due to enzyme alpha-iduronidase deficiency has generally a spectrum of findings involving the eye, skeletal abnormality, organomegaly, joint stiffness, hernia, mental retardation and cardiovascular abnormalities. The two cases presented here are related to each other as brother of 9 years age and sister of 7 years of age with their parents had consanguineous marriage. On ocular examination in both the cases there was dense bilateral corneal opacities. Glycosaminoglycan's level was found to be 4 mg/mmol cr in the first case and 5 mg/mmol cr in the second case. In the first case no ocular treatment was planned and in the second case penetrating keratoplasty was the choice of management.

Congenital hypothyroidism (CH) is the commonest treatable cause of mental retardation. The prevelance is 1/3000 - 1/4000 live births worldwide. The importance of CH is that, the longer the diagnosis of CH is delayed, the higher the risk of mental retardation and neurologic sequale; such as poor motor coordination, ataxia, spastic diplegia, muscular hypotonia, strabismus, learning disability and diminished attention span. The most common cause of permenant CH is thyroid dysgenesis (85-90%) in which the transcription factors TTF1,TTF2 and PAX8 would appear to be obvious candidate genes in the aetiology. Especially cardiac defects and some other birth defects are described in patients with CH. Inborn errors of thyroid hormonogenesis are responsible for 10-15% of CH cases and usually have autosomal recessive inheritance, consistent with a single gene mutation. Transient CH is very common in prematures with an estimate of 10% of CH babies identified on newborn screening, or 1 in 40,000 neonates. CH neonates are usually symptom-free and the most encountered symptoms are prolonged jaundice, large fontanelles and umbilical hernia. In general, the extent of clinical findings depends on the cause, severity and duration of hypothyroidism. An elevated TSH>20 microm Iu/L and a decreased concentration of T4 confirms the diagnosis of CH. Infants with permanant abnormalities of thyroid function mostly have a serum TSH concentration > 50 microm Iu/L. Ultrasonography, thyroid scintigraphy, bone x ray of the knee and serum thyroglobulin concentration are the other essentials after diagnosis to clarify the status of the thyroid and the severity of hypothyroidism. The higher doses of 10- 15 microm g/kg/day and the commencement of treatment before 2 weeks gave rise to better long term outcome of CH patients. In the follow up of the patients noncompliance is the most important problem and serum freeT4 or T4 and TSH should be obtained at each visit to adjust the doses of L-thyroxine. Still a small number of patients with severe hypothyroidism in utero or reflected by clinical signs and symptoms extremely low T4 levels and delayed bone age may have intellectual deficits despite normal intelligence.

We describe a 3-year-old boy with complete agenesis of corpus callosum, developmental delay/mental retardation, anterior diaphragmatic hernia, Morgagni type, severe hypermetropia, and facial dysmorphism suggesting the diagnosis of Donnai-Barrow syndrome. Subtelomeric FISH analysis revealed a paternally-derived t(9;16) (q34.3;q24.3) translocation with partial 9q monosomy and partial 16q trisomy. As some facial features resemble the 9q emerging phenotype, we suggest the hypothesis that some patients with Donnai-Barrow syndrome might be abscribed to 9q terminal deletion.

Pallister-Killian Syndrome (PKS) is a rare sporadic congenital anomaly disorder, characterized by multiple congenital anomalies, especially craniofacial dysmorphism. It is also associated with mental retardation, seizure, skin pigmentation, and visceral malformations such as congenital diaphragmatic hernia, congenital heart defect, anorectal anomalies, and genital malformation. This syndrome usually presents with tissue-limited mosaicism of supernumerary 12p isochromosome i (12p). Moreover, diagnosis of Pallister-Killian Syndrome (PKS) is difficult because the ratio of abnormal to normal karyotyping is much lower in peripheral lymphocytes than in skin fibroblasts. We report the first case in Taiwan, who has tetrasomy 12p mosaic in peripheral lymphocytes.

Anomalies in WT-1 (Wilms' tumor gene), mapped to 11p13, cause Denys-Drash, Frasier and WAGR syndromes. WAGR syndrome is characterized by Wilms' tumor (W), aniridia (A), genitourinary anomalies (G) and mental retardation (R). In the early human fetus, WT-1 is expressed in the pleural and abdominal mesothelium, and consequently this gene may play a role in diaphragm development. The first report of an association between WAGR syndrome and congenital diaphragmatic hernia has recently been published. We present another infant with aniridia, left cryptorchidism with testicular dysgenesis, right-sided posterolateral diaphragmatic hernia and moderate psychomotor retardation, in whom genetic study showed a deletion of 11p13 and PAX-6, confirming the diagnosis of WAGR syndrome.
